Provide RESET and Power regulators for the USB PHY,
the USB Host port mode and the PHY device.

Also provide pin multiplexer information for USB host
pins.

Rev. Ax/Bx boards have reversed polarity for USBHOST_PWR_ENable
signal when compared to Rev. C boards.

We create a new dts file for Ax/Bx boards.

Also update model and compatible flags for Rev. C board.
