This and it also provides a reg space where we can get/set the
performance state.

I think yes we can make it work through that as well, but I am not
sure if we will be able to use required-opp n stuff here as the DT
doesn't have the OPP table for the CPUs.

The CPU's freq table is generated at runtime, see
drivers/cpufreq/mediatek-cpufreq-hw.c for example.
