Allowing these GDSCs to collapse makes the QMP combo PHYs lose their
configuration on machine suspend. Currently, the QMP combo PHY driver
doesn't reinitialise the HW on resume. Under such conditions, the USB
SuperSpeed support is broken. To avoid this, mark the pwrsts flags with
RET_ON. This has been already done for USB 0 and 1 SS PHY GDSCs,
Do this USB MP SS1 PHY GDSC config. The USB MP SS1 PHY GDSC already has
it.
