This follows the sparc changes a439fe51.

Most of the moving about was done with Sam's directions at:

with subsequent hacking and fixups entirely my fault.

Add SuperH specific funcion clk_always_enable(), useful to enable MSTPCR
bits in processor or board specific code.

Add arch_flags to struct clk so we can keep per-clock private data
somewhere and share code between multiple clocks.

This patch contains the following cleanups:
- make the following needlessly global code static:
  - cf-enabler.c: cf_init()
  - cpu/clock.c: __clk_enable()
  - cpu/clock.c: __clk_disable()
  - process_32.c: default_idle()
  - time_32.c: struct clocksource_sh
  - timers/timer-tmu.c: struct tmu_timer_ops
- remove the following unused functions (no CONFIG_BLK_DEV_FD on sh):
  - process_{32,64}.c: disable_hlt()
  - process_{32,64}.c: enable_hlt()

This is an optional component of the clock framework. However,
as we're going to be using this in the cpufreq drivers, add
support for it to the framework.

Previously this was done in cpuinfo, but with the number of clocks
growing, it makes more sense to place this in a different proc entry.

This adds support for the SH7722 (MobileR) to the clock framework.

This syncs up the SH clock framework with the linux/clk.h API,
for which there were only some minor changes required, namely
the clk_get() dev_id and subsequent callsites.

This adds a relatively simplistic clock framework for sh.  The initial goal
behind this is to clean up the arch/sh/kernel/time.c mess and to get the CPU
subtype-specific frequency setting and calculation code moved somewhere more
sensible.

This only deals with the core clocks at the moment, though it's trivial for
other drivers to define their own clocks as desired.
