ARM: OMAP: Sync headers with linux-omap
This patch syncs omap specific headers with linux-omap. Most of the changes needed because of bitrot caused by driver changes in linux-omap tree. Integrating this is needed for adding support for various omap drivers. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
