Add support for qcs404 on nvmem driver.
The qcs404 SoC has support for Core Power Reduction (CPR), which is
implemented as a power domain provider, therefore add optional support
in this driver to attach to a genpd power domain.

Refactor the driver to make it easier to extend in a later commit.
Create a driver struct to collect all common resources, in order to make
it easier to free up all common resources.
Create a driver match_data struct to make it easier to extend the driver
with support for new features that might only be supported on certain SoCs.

The kryo cpufreq driver reads the nvmem cell and uses that data to
populate the opps. There are other qcom cpufreq socs like krait which
does similar thing. Except for the interpretation of the read data,
rest of the driver is same for both the cases. So pull the common things
out for reuse.
