[PATCH v2 2/2] ARM: dts: omap3-beagle-xm: Add USB host supprot for Rev. Ax/Bx

[Roger Quadros <rogerq@ti.com>]

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.
