usb: chipidea: add hw_wait_phy_stable for getting stable status

Browse source

The phy needs some delay to output the stable status from low
power mode. And for OTGSC, the status inputs are debounced
using a 1 ms time constant, so, delay 2ms for controller to get
the stable status(like vbus and id) when the phy leaves low power.
