OMAP: Add new function to check wether there is irq pending
Add common omap2/3 function to check wether there is irq pending. Switch to use it in omap2 pm code instead of its own. Signed-off-by: Jouni Hogander <jouni.hogander@nokia.com> Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Kevin Hilman <khilman@deeprootsystems.com>
