usb: dwc3-msm: Release PM wakelock in host mode only for auto targets
Currently the driver releases PM wakelock in host mode. This
causes pm_suspend to get triggered. Although pm_suspend bails out
but xhci_bus_suspend transitions the bus to a bad state leading
to host mode failure.
Fix this by releasing wakelock only for targets on which we allow
PM suspend in host mode irrespective of runtimePM.
