usb: ehci-orion: avoid double PHY initialization

Browse source

No need to initialize the PHY from the driver's probe. It is done by
the core automatically and doing it twice would increment the
phy->powercount counter to 2 instead of 1. During later suspend
operation, the counter will be decremented to one, no phy->power_off()
will occur and worse than that, the following phy->power_on() at
resume time will also be skipped, failing the whole S2RAM operation.
