MSM8996 Pro (also known as MSM8996SG) is a newer revision of MSM8996
with different CPU/CBF/GPU frequencies and CPR parameters. Its CBF clock also
has a different divisor.

This series handles the difference in the CBF clock and adds a new DTSI for
MSM8996 Pro with CPU and GPU OPPs. It also removes reading msm-id from SMEM
in qcom-cpufreq-nvmem as it becomes no longer necessary. Separating MSM8996
and MSM8996 Pro will help with implementing CBF scaling and CPR; since they
have different CPR parameters and CPU:CBF OPP mapping which is difficult to
implement in the same cluster OPP tables.
