This commit is based on previous work by Robert Baldyga which can be found at [1]; however that patch turned out to have a high probability of regressing many UDC drivers because of a blind search & replace s/driver/$udc->driver/ which caused the 'driver' argument to stop_activity() to be a valid non-NULL pointer when it should be NULL, thus causing UDCs to mistakenly call gadget driver's ->disconnect() callback.

The USB PHY member of the OTG structure is renamed to 'usb_phy' and modifications are done in all drivers accessing it. Renaming this pointer will allow to keep the compatibility for USB PHY drivers.

In some cases this port power can not be just toggled by the PORT_POWER bit, and the gpio-regulator is needed to be toggled too. This patch defines a port power control interface ehci_port_power for ehci core use, it toggles PORT_POWER bit as well as calls platform defined .port_power if it is defined.
