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.

In commit 78d77df715 ("x86-64, init: Do not set NX bits on non-NX
capable hardware") we added the early_pmd_flags that gets the NX bit set
when a CPU supports NX. However, the new variable was marked __initdata,
because the main _use_ of this is in an __init routine.
However, the bit setting happens from secondary_startup_64(), which is
called not only at bootup, but on every secondary CPU start. Including
resuming from STR and at CPU hotplug time. So the value cannot be
__initdata.
