[PATCH 18/30] ARM: OMAP: AM3517crane: Adapt to ehci-omap changes

[Roger Quadros]

Add platform device for 'nop-usb-xceiv'. This will be used as a
PHY for HS USB Port 1, so provide binding information for it.

Model RESET and Power for HS USB Port 1 as GPIO fixed regulators
and link them to the 'nop-usb-xceiv' PHY.
