The series adds missing vdd-supply for QUSB2 PHY which is required for
digital circuit.  The driver works right now likely because firmware
already sets it up.  Add it to bindings, driver and DTS that miss the
supply.

It should not cause problem for existing DTBs:
- SC7180, SDM630, SDM845 based platforms already specified vdd-supply
  in the DTBs.
- MSM8996 and MSM8998 platform DTBs miss vdd-supply, but dummy regulator
  will ensure QUSB2 PHY driver works as before on these platforms.
