USB: dwc3_otg: Move to A_IDLE state if unable to start host
As part of ID clear, OTG driver tries to start host mode. This may
fail if regulator driver is not ready and returns -EPROBE_DEFER
for VBUS regulator_get. Instead of moving to UNDEFINED state, move
OTG state-machine to A_IDLE so that it can retry start_host later
when notified again as part of regulator driver's initialization.
