Now that we've gotten rid of clk_readl() we can remove io.h from the
clk-provider header and push out the io.h include to any code that isn't
already including the io.h header but using things like readl/writel,
etc.

I also reordered a couple includes when they weren't alphabetical and
removed clk.h from kona, replacing it with clk-provider.h because
that driver doesn't use clk consumer APIs.

We'd like to privatize __clk_get(), but the sunxi clk driver is
calling this function to keep a reference held on the clk and
call clk_prepare_enable() on it. We support this design in the
clk core now with the CLK_IS_CRITICAL flag, so let's just use
that instead.

The .get_factors callback of factors_clk has 6 parameters. To extend
factors_clk in any way that requires adding parameters to .get_factors
would make that list even longer, not to mention changing all the
function declarations.
Do this once now and consolidate all the parameters into a struct.
Also drop the space before function pointer arguments, since checkpatch
complains.

This driver builds based on obj-y and hence will not ever be
modular. Change it to use the non-modular registration so that it
won't suffer a compile fail once a header move places the modular
registration within the module.h file.

The module 0 style clocks, or storage module clocks as named in the
official SDK, are almost the same as the module 0 clocks on earlier
Allwinner SoCs. The only difference is wider mux register bits.
As with earlier Allwinner SoCs, mmc module clocks are a special case
of mod0 clocks, with phase controls for 2 child clocks, output and
sample.
This patch adds support for both.

The only difference between module clocks on different platforms is the
width of the mux register bits and the valid values, which are passed in
through struct factors_data. The phase clocks parts are identical.
This patch generalizes the setup function, so most of the code can be
reused when adding sun9i support, which has a wider mux register.

Instead of having three different clocks for the main MMC clock and the two

With the prcm in sun6i (and some later SoCs) some mod0 clocks are instantiated
through the mfd framework, and as such do not work with of_clk_declare, since
they do not have registers assigned to them yet at of_clk_declare init time.
Silence the error on not finding registers in the of_clk_declare mod0 clk
setup method, and also register mod0-clk support as a platform driver to work
properly with mfd instantiated mod0 clocks.

Before this commit sunxi_factors_register uses of_iomap(node, 0) to get
the clk registers. The sun6i prcm has factor clocks, for which we want to
use sunxi_factors_register, but of_iomap(node, 0) does not work for the prcm
factor clocks, because the prcm uses the mfd framework, so the registers
are not part of the dt-node, instead they are added to the platform_device,
as platform_device resources.
This commit makes getting the registers the callers duty, so that
sunxi_factors_register can be used with mfd instantiated platform device too.
While at it also add error checking to the of_iomap calls.
This commit also drops the __init function from sunxi_factors_register since
platform driver probe functions are not __init.

Some of the factors-style clocks on the A80 have different widths
for the mux values in the registers.
Add a .muxmask field to clk_factors_config to make it configurable.
Passing a bitmask instead of a width parameter will allow reuse
in case we support table-based muxes in the future.

The MMC clock we thought we had until now are actually not one but three
different clocks.
The main one is unchanged, and will have three outputs:
- The clock fed into the MMC
- a sample and output clocks, to deal with when should we output/sample data
to/from the MMC bus
The phase control we had are actually controlling the two latter clocks, but
the main MMC one is unchanged.
We can adjust the phase with a 3 bits value, from 0 to 7, 0 meaning a 180 phase
shift, and the other values being the number of periods from the MMC parent
clock to outphase the clock of.
