Commit Message

  The sc7180 phy compatible works fine for some cases, but it turns out
sm6350 does need proper phy configuration in the driver, so use the
newly added sm6350 compatible.

Because the sm6350 compatible is using the new binding, we need to
change the node quite a bit to match it.

This fixes qmpphy init when no USB cable is plugged in during bootloader
stage.

Changes since v2:
* Rebase on https://lore.kernel.org/all/20221111094729.11842-2-johan+linaro@kernel.org/
  While this commit deletes the changes there it's still good to get it
  in for completeness
* Fix clocks, add power-domain

These have been switched too.

Looks good otherwise. With the resets fixed you can add my:
