Enable the cmu-peric1 clock controller. It feeds additional USI, I3C
and PWM interfaces / busses.

Note that &sysreg_peric1 needs a clock to be able to access its
registers and now that Linux knows about this clock, we need to add it
in this commit as well so as to keep &sysreg_peric1 working, so that
the clock can be enabled as and when needed.
