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 with the introduction.
of a separate device tree. Separating MSM8996 and MSM8996 Pro will help with
implementing CBF scaling and CPR; as they have different CPR parameters
and CPU:CBF OPP mapping which is difficult to implement in the same cluster
OPP tables.

Dependencies:

- arm64: dts: qcom: msm8996: Add support for the CBF clock
  https://lore.kernel.org/linux-arm-msm/20210528192541.1120703-2-konrad.dybcio@somainline.org/

Changes since v1:
- Rebase DT changes on already merged patches[1][2].
- Add more details to commit messages.
- Split removing MSM8996 Pro speed bin bits from opp-supported-hw into
  a separate patch.
- Rename msm8996-xiaomi-scorpio.dts to msm8996pro-xiaomi-scorpio.dts
