Now that everything has converted over to generic timekeeping, we need an
alternate method for keeping the RTC updated for those platforms that are
still using the rtc_sh_get/set_time pairs, presently limited to SH-03 and
the Dreamcast. This wires up the GENERIC_CMOS_UPDATE hooks for those to
maintain the same behaviour.

Presently this is special-cased for early initialization. While there are
situations where these static early initializations are still necessary,

patch we simplify the MMU less case with a pass through version of

This patch moves the SuperH timer setup code from time_init()
to late_time_init(). Good things about this change:
 - interrupts: they are enabled at late_time_init()
 - mm: regular kmalloc() can be used at late_time_init()

Together with moving to late_time_init() this patch changes
the sh_cmt driver to always allocate with kmalloc(). This
simplifies the code a bit and also fixes section mismatches.
