with support for other Renesas ARM and arm64 based SoCs.

This is a follow-up for a similar change that has already been accepted
for the r8a7795.


I have provided an integration branch that includes with this patch, those
DTS updates that make use of opp-v2 bindings that depend on this change,
and Renesas clock updates also depended on by the DTS changes.  The result
is working CPUFreq for the r8a7796 (R-Car M3-W).

A description of steps taken to lightly exercise the same feature for the
r88a7795 the above can be found at the link below. The results are the same
for the r8a7796 with the exception that it has two active CPU cores rather
than four.
