This fixes up a typo in the ll/sc based cmpxchg code which apparently
wasn't getting a lot of testing due to the swapped old/new pair. With
that fixed up, the ll/sc code also starts using it and provides its own
atomic_add_unless().

This patch rewrites the sh7722 clock framework code.
The new code makes use of the recently merged div4,
div6 and mstp32 helper code. Both extal and dll are
supported as input clocks to the pll.

While at it, now when all SuperH Mobile processors
are converted, fix CONFIG_SH_CLK_CPG_LEGACY to depend
on CONFIG_ARCH_SHMOBILE.
