linux-omap3-pm: OMAP3 kernel recipe to build Kevin Hilman's linux-omap-pm tree

Currently tested on Zoom2 and Beagle board.  Please test if you have an OMAP3
board!  The source tree for this recipe is the latest and greatest power
management code for OMAP3.  You can find it at
http://git.kernel.org/?p=linux/kernel/git/khilman/linux-omap-pm.git;a=summary
