MSM8996 Pro has a /4 post divisor on its CBF PLL instead of /2, allowing
it to reach 192000000Hz on the lowest CPU OPPs (compared to 307200000Hz
on MSM8996). Add a compatible string to differentiate between the two and
handle the different divisor in the driver. Finally, add peak bandwidths
to CPU OPPs in msm8996pro.dtsi.

This series depends on the following patch series:
  clk: qcom: msm8996: add support for the CBF clock
  https://lore.kernel.org/linux-arm-msm/20230410200014.432418-1-dmitry.baryshkov@linaro.org/

Changes since v1:
  - Patch structs during probe instead of defining new ones.
