Subject: [PATCH 15/20] phy: qcom-qmp-combo: drop start and pwrdn-ctrl abstraction

All USB PHYs need to start and stop the SerDes and PCS so drop the
start-ctrl abstraction which is no longer needed since the QMP driver
split.

Similarly, drop the pwrdn-ctrl abstraction which also is not needed
since the split.
