UBUNTU: SAUCE: ARM: OMAP: Add macros for comparing silicon revision

BugLink: http://bugs.launchpad.net/bugs/608095

Adapted from arago project patch by Sanjeev Premi <premi@ti.com>

This helps provide the required setup to enable USB Ethernet (usb0) and
USB host on the XM Beagleboard (A rev).  This will be submitted upstream
by Steve Sakoman.
