Tony Lindgren 9ad5897c26 [ARM] 3143/1: OMAP 4/5: Update omap include files 
Patch from Tony Lindgren

This patch syncs the mainline kernel with linux-omap tree.

This patch contains changes to common header files for
omap1xxx and omap24xx by various omap developers, and
improved cpu detection by Imre Deak
