Add support to gate the clocks that directly feed peripherals. For clocks
with multiple parents, add the ability to determine the correct parent,
and also set parents. Also add support to calculate and set the clocks'
rate.

An earlier commit "ARM: shmobile: sh73a0: add support for adjusting CPU
frequency" intended to replace some clock operations only for the Z-clock,
instead it replaced them for all div4 clocks, since all div4 clocks share
the same copy of clock operations. Fix this by using a separate clock
operations structure for Z-clock.

Break out the function sh73a0_init_delay() that now
gets called both for the C version of the code and
the DT -reference boards. This way we handle both
cases in the same way.

Allows us to boot with TWD only in the kernel configuration
for C board code. TWD is not yet enabled in the case of
DT -reference - this due to a dependency on CCF.
