We need a lot of imx6 specific things into common esdhc_set_clock
for support SD3.0 and eMMC DDR mode which is not needed for power pc
platforms, so esdhc_set_clock seems not so common anymore.
Instead of keeping add platform specfics things into this common API,
we choose to move that code into platform driver itself to handle.
This can also exclude the dependency between imx and power pc on this
headfile and is easy for maintain in the future.

The tuning of some platforms may not follow the standard host control
spec v3.0, e.g. Freescale uSDHC on i.MX6Q/DL.
Add a hook here to allow execute platform specific tuning instead of
standard host controller tuning.
The hook only replaces the tuning process, so it's placed after tuning
checking and before the real tuning process.
Some notes for the tuning hook:
1) it needs handle lock itself if it wants to access host controller
according platform specific implementation.
2) do not need to handle runtime pm since it executes with runtime pm
get already.

This avoid duplicated implementation and also fixes missing iounmap() and
release_mem_region() calls in sdhci_bcm_kona_remove(). sdhci_pltfm_init()
calls request_mem_region() and ioremap(), thus we need to call the
corresponding iounmap() and release_mem_region() calls in
sdhci_bcm_kona_remove().

In IDMAC mode EVENT_XFER_COMPLETE is set when RI/TI of last descriptor
is done. So if errors are happened in the middle of data transfers,
'dw_mci_stop_dma' during error handing can be called and eventually
prevents this flag to be set. This results in permanent wait for
EVENT_XFER_COMPLETE in 'dw_mci_tasklet_func'. Therefore, if dma
running is stopped forcibly, EVENT_XFER_COMPLETE should be set.

Exynos's host has divider logic before 'cclk_in' to controller core.
It means that actual clock rate of ciu clock comes from this divider
value. So, source clock should be adjusted along with 'ciu_div' which
indicates the host's divider ratio. Setting clock rate basically fits
the required speed. Specially, 'cclk_in' should have double rate of
target speed in case of DDR 8-bit mode.

Previously the dw_mmc driver would ignore any requests to disable the
card's clock. This doesn't seem like a good thing in general, but had
one extra bad side effect in the following situation:
* mmc core would set clk to 400kHz at boot time while scanning
* mmc core would set clk to 0 since no card, but it would be ignored.
* suspend to ram and resume; clocks in the dw_mmc IP block are now 0
but dw_mmc thinks that they're 400kHz (it ignored the set to 0).
* insert card
* mmc core would set clk to 400kHz which would be considered a no-op.
Note that if there is no card in the slot and we do a suspend/resume
cycle, we _do_ still end up with differences in a dw_mmc register
dump, but the differences are clock related and we've got the clock
disabled both before and after, so this should be OK.

The MMC subsystem handles looking for a card at probe time. Queuing up our
own can race with the rest of the MMC subsystem and cause problems if we
get unlucky with timing. Just remove driver own detection triggering. While
progressing the request from 'mmc_rescan', if 'dw_mci_work_routine_card'
routine is activated, it will cancel the current request. The problem case
is that 'mmc_rescan' is prior to 'dw_mci_work_routine_card' from host own.
Specifically, the following message shows the detection problem in driver's
probing. It would get an err -123 (-ENOMEDIUM) during probe.

If a corresponding power domain exists for the device and it manages
to cut the domain regulator while the device is runtime suspended,
the IP loses it's registers context. We restore the context in the
.runtime_resume callback from the existing register caches to adapt
to this situation.
We also want to make sure the registers are in a known state while
restoring context in the case when the power domain did not drop the
power, since there are restrictions for the order of writing to these
registers. To handle this, we clear the registers in the
.runtime_suspend callback.

After a write to the MMCICLOCK register data cannot be written to this
register for three feedback clock cycles. Writes to the MMCIPOWER
register must be separated by three MCLK cycles. Previously no issues
has been observered, but using higher ARM clock frequencies on STE-
platforms has triggered this problem.
The MMCICLOCK register is written to in .set_ios and for some data
transmissions for SDIO. We do not need a delay at the data transmission
path, because sending and receiving data will require more than three
clock cycles. Then we use a simple logic to only delay in .set_ios and
thus we don't affect throughput performance.

drops the domain regulator.

Pull ARM SoC board updates from Olof Johansson:
"Board updates for 3.12. Again, a bit of domain overlap with SoC and
DT branches, but most of this is around legacy code and board support.
We've found that platform maintainers have a hard time separating all
of these out and might move towards fewer branches for next release.
- Removal of a number of Marvell Kirkwood board files, since contents
is now common and mostly configured via DT.
- Device-tree updates for Marvell Dove, including irqchip and
clocksource setup.
- Defconfig updates. Gotta go somewhere. One new one for Renesas
Lager.
- New backlight drivers for backlights used on Renesas shmobile
platforms.
- Removal of Renesas leds driver.
- Shuffling of some of the new Broadcom platforms to give room for
others in the same mach directory. More in 3.13"

The default phase can meet most cards' requirement, but it is not the
optimal one. In some extreme situation, the rx phase point produced by
the following tuning process will drift quite a distance.
Before tuning UHS card, this patch will set a more proper initial tx
phase point, which is calculated from statistic data, and can achieve
a much better tx signal quality.
