[U-Boot] [RFC] [PATCH] omap3_beagle: fdt: xMA/B set hsusb2_power_reg active-high

[Robert Nelson]

With the xM revision C, the DC control of the usb hub was inverted.

By adding the enable-active-high property to hsusb2_power_reg, mainline omap3-beagle-xm.dtb
will now activiate properly activate the usb hub on older xMA/B varients.
