Move the ramc initialization to pm.c as it is the only user left.
This allows us to get rid of at91_dt_initialize() that was the only one called
by the init_early() function pointer of struct machine_desc.

Only use SOC_AT91SAM9 for all the at91sam9 SoCs. It removes all the empty
at91sam9xxx.c SoC files. It also removes the useless at91_init_soc affectation
procedure and its "init" function pointer.
Only the SoC detection and display are kept for the at91sam9:
at91_soc_is_enabled() and at91_boot_soc.map_io() function calls are also
removed.
It enables HAVE_AT91_SMD and HAVE_AT91_UTMI for all the sam9 SoCs but this only
represents 96 bytes of uncompressed kernel code.

This patch adds required definitions and structures for clockdomain

new ti81xx_clockdomains_init() while early initialization of

This adds a device tree controlled option to enable PMC-based
thermal reset in overheating situations. Thermtrip is supported on
Tegra30, Tegra114 and Tegra124. The thermal reset only works when
the thermal sensors are calibrated, so a soctherm driver is also
required.
The thermtrip event is triggered by the soctherm block, and all
soctherm sensors default to showing a temperature of zero Celsius
before they are initialized. Because of this, it is safe to initialize
thermtrip and soctherm in any order.

The mvebu-mbus driver reads the SDRAM window registers, and make the
information about the DRAM CS configuration available to device
drivers using the mv_mbus_dram_info() API. This information is used by
the DMA-capable device drivers to program their address decoding
windows.
Until now, we were basically providing the SDRAM window register
details as is. However, it turns out that the DMA capability of the
CESA cryptographic engine consists in doing DMA being the DRAM and the
crypto SRAM mapped as a MBus window. For this case, it is very
important that the SDRAM CS information does not overlap with the MBus
bridge window.
Therefore, this commit improves the mvebu-mbus driver to make sure we
adjust the SDRAM CS information so that it doesn't overlap with the
MBus bridge window. This problem was reported by Boris Brezillon,
while working on the mv_cesa driver for Armada 37x/38x/XP. We use the
memblock memory information to know where the usable RAM is located,
as this information is guaranteed to be correct on all SoC variants.
We could have used the MBus bridge window registers on Armada 370/XP,
but they are not really used on Armada 375/38x (Cortex-A9 based),
since the PL310 L2 filtering is used instead to discriminate between
RAM accesses and I/O accesses. Therefore, using the memblock
information is more generic and works accross the different platforms.

On Armada XP, 375 and 38x the MBus window 13 has the remap capability,
like windows 0 to 7. However, the mvebu-mbus driver isn't currently
taking into account this special case, which means that when window 13
is actually used, the remap registers are left to 0, making the device
using this MBus window unavailable.
To make things even more fun, the hardware designers have chosen to
put the window 13 remap registers in a completely custom location,
using a logic that differs from the one used for all other remappable
windows.
To solve this problem, this commit:
* Adds a SoC specific function to calculate offset of remap registers
to the mvebu_mbus_soc_data structure. This function,
->win_remap_offset(), returns the offset of the remap registers, or
MVEBU_MBUS_NO_REMAP if the window does not have the remap
capability. This new function replaces the previous integer field
num_remappable_wins, which was insufficient to encode the special
case of window 13.
* Adds an implementation of the ->win_remap_offset() function for the
various SoC families. Some have 2 first windows that are remapable,
some the 4 first, some the 8 first, and then the Armada XP/375/38x
case where the 8 first are remapable plus the special window
13. This is implemented in functions
generic_mbus_win_remap_2_offset(),
generic_mbus_win_remap_4_offset(),
generic_mbus_win_remap_8_offset() and
armada_xp_mbus_win_remap_offset() respectively.
* Change the code to use the ->win_remap_offset() function when
accessing the remap registers, and also to use a newly introduced
mvebu_mbus_window_is_remappable() helper function that tells
whether a given window is remapable or not.
* Separate Armada 370 from XP/375/38X because the window 13 of Armada
370 does not support the remap capability.
