Pass clocksource pointer to the read() callback for clocksources. This
allows us to share the callback between multiple instances.

Extend the 32-bit SuperH timer code to register and probe
the earlytimer class of Early Platform Drivers.
This registers the sh_cmt driver if compiled-in.

GENERIC_TIME still depends on the clocksource bits being there, which is
presently not supported. This allows the CMT clockevent driver to be used
alongside alternate system timers that do not yet provide a clocksource
of their own (MTU2 and so on in the case of SH-2A).

Handle the case with a sys_timer set to NULL.

Rework and simplify the sched_clock and clocksource code. Instead
of registering the clocksource in a shared file we move it into the
tmu driver. Also, add code to handle sched_clock in the case of no
clocksource.

Nothing is using this any more, so get rid of it before anyone gets the
bright idea to start using it again.

This migrates from the old bitrotted kgdb stub implementation and moves
to the generic stub. In the process support for SH-2/SH-2A is also added,
which the old stub never provided.

The dummy timer needs to be registered on the boot CPU before the
system timer clockevent is registered, or broadcasting doesn't work
as advertized.

This hooks up GENERIC_CLOCKEVENTS_BROADCAST and a dummy local timer,
which we call in to from the timer IPI when no other local timer is
provided.

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()
