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.

What about the rest.. I checked SM8350 and SM8250 mtp ones are missing
this. With the property made mandatory, I guess it would cause these to
fail right..

From what I can see, SM8350 and SM8250 use qcom-snps-femto-v2 PHY
rather than qcom-qusb2.  So they should not be affected by this series.
