sh: move sh clock.c contents to drivers/sh/clk.

This patch is V2 of the SH clock framework move from
arch/sh/kernel/cpu/clock.c to drivers/sh/clk.c. All
code except the following functions are moved:
clk_init(), clk_get() and clk_put().

The init function is still kept in clock.c since it
depends on the SH-specific machvec implementation.

The symbols clk_get() and clk_put() already exist in
the common ARM clkdev code, those symbols are left in
the SH tree to avoid duplicating them for SH-Mobile ARM.

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.

sh: clkfwk: Provide a generic clk_set_rate_ex() path for root clocks.

In the case of root clocks (such as clkin oscillators, extal, etc.), the
rate information is entirely platform dependent and needs to be lazily
set and propagated from the platform code. This provides a method for
establishing the rate update on these types of clocks that define no
set_rate() op of their own.
