Few fixes for omaps to allow am437x only builds to boot properly with

CPU_IDLE and ARM TWD timer. This is probably a common configuration setup
 for people making products with these SoCs so let's make sure it works.
 
 Also a wakeirq fix for duovero parlor making my life a bit easier as that
 allows me to run basic PM regression tests on it.
 
 It would be nice to have these in v4.4, but if it gets too late for that
 because of the holidays, it is not super critical if these get merged for
 v4.5.
