sh: timer rewrite V5

SuperH Timer Rewrite V5:

[PATCH 01/03] sh: CONFIG_SH_TIMER support
[PATCH 02/03] sh: CMT early platform driver
[PATCH 03/03] sh: enable CMT on sh7723/sh7722/sh7366/sh7343

This patchset is another iteration which simply disconnects the clocksource patches and makes use of early platform drivers. The early platform driver patch and read(), enable/disable() and arch_gettimeoffset clocksource patches can be found on lkml.
