sh: Mass ctrl_in/outX to __raw_read/writeX conversion.

The old ctrl in/out routines are non-portable and unsuitable for
cross-platform use. While drivers/sh has already been sanitized, there
is still quite a lot of code that is not. This converts the arch/sh/ bits
over, which permits us to flag the routines as deprecated whilst still
building with -Werror for the architecture code, and to ensure that
future users are not added.

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.

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.

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.
