Commit Message

With PWRSTS_OFF_ON, PCIe GDSCs are turned off during gdsc_disable(). This
can happen during scenarios such as system suspend and breaks the resume
of PCIe controllers from suspend.

So use PWRSTS_RET_ON to indicate the GDSC driver to not turn off the GDSCs
during gdsc_disable() and allow the hardware to transition the GDSCs to
retention when the parent domain enters low power state during system
suspend.
