The MSM DSI PHY drivers currently hardcode the name and the rate of
the PHY ref clock. Get the ref clock from the device tree instead.

Note: testing of this series was limited to SDM845 and the 10nm PHY

Major changes in v5:
- none (see per-patch change log for minor changes)

Major changes in v4:
- always use parent rate for 28nm and 28nm 8960 PHYs

Major changes in v3:
- keep supporting DTs without ref clock for the 28nm and the 28nm
  8960 PHYs
- added patch to add ref clock to qcom-apq8064.dtsi

Major changes in v2:
- apply to all MSM DSI PHY drivers, not only 10nm
