This adds support for the SH7263 (SH-2A) CPU.

This particular CPU is a superset of SH7203, adding some additional
peripheral blocks and hooking up additional (reserved on SH7203)
vectors in the INTC block.

No visibly nasty surprises, yet..

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.

Since all of the sys_timer sources currently do this on their own
within the ->get_offset() path, it's more sensible to just have
the caller take care of it when grabbing xtime_lock. Incidentally,
this is more in line with what others (ie, ARM) are doing already.

All of the various CPU subtypes currently hardcode TIMER_IRQ,
switch this to a config option in the few places we need this.

This allows further removal of hardcoded IRQ headers..

A number of API changes happened underneath the 7206 patches, update
for everything that broke.
