ba9a633787 sh: convert processor device setup functions to arch_initcall()
Convert the processor platform device setup
functions from __initcall() and sometimes
device_initcall() to arch_initcall().

This makes sure that the platform devices are
registered a bit earlier so the devices are
available when drivers register using initcall
levels earlier than device_initcall().

A good example is platform devices needed by
i2c-sh_mobile.c which registers a bit earlier
using subsys_initcall().

2eb2a43682 sh: SH7786 SMP support.
SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2
CPUs. This just wraps in to the existing SH-X3 SMP code with some minor
changes for SH7786, including wiring up the IPIs properly, enabling
IRQ_PER_CPU, and so forth.

cc96eace48 sh: clkfwk: rate table construction and rounding for SH7785.
This adds support for constructing a rate table by looking at potential
divisors for a specified clock. Each FQRMR clock is given its own table.
Presently each table is rebuilt when the parent propagates down a new
rate, so some more logic needs to be added to do this more intelligently.

Additionally, a fairly generic round_rate() implementation is then
layered on top of it, which subsequently provides us with cpufreq support.

9fe5ee0efb sh: clkfwk: Use arch_clk_init() for on-chip clock registration.
CPUs registering on-chip clocks should be using arch_clk_init() with the
new scheme so that the CPUs have the opportunity to establish the
topology prior to the initial root clock rate propagation. This ensures
that CPUs with on-chip clocks that use CLK_ENABLE_ON_INIT are properly
enabled at the initial propagation time, without having to further poke
the root clocks.

there is no longer any need for the special clk_recalc_rate(), so we kill

f5c84cf508 sh: clkfwk: Tidy up on-chip clock registration and rate propagation.
This tidies up the set_rate hack that the on-chip clocks were abusing to
trigger rate propagation, which is now handled generically.

Additionally, now that CLK_ENABLE_ON_INIT is wired up where it needs to
be for these clocks, the clk_enable() can go away. In some cases this was
bumping up the refcount higher than it should have been.

4ff29ff8e8 sh: clkfwk: Consolidate the ALWAYS_ENABLED / NEEDS_INIT mess.
There is no real distinction here in behaviour, either a clock needs to
be enabled on initialiation or not. The ALWAYS_ENABLED flag was always
intended to only apply to clocks that were physically always on and could
simply not be disabled at all from software. Unfortunately over time this
was abused and the meaning became a bit blurry.

So, we kill off both of all of those paths now, as well as the newer
NEEDS_INIT flag, and consolidate on a CLK_ENABLE_ON_INIT. Clocks that
need to be enabled on initialization can set this, and it will purposely
enable them and bump the refcount up.
