Fixes for omaps 

A series of fixes for omap variants for minor issues, and a fix for a timer
 regression for some omap3 beagleboard versions.
 
 The timer fix needs to patch both the dts and the timer code because
 otherwise the timer quirk handling for old dtbs will prevent the dts fix
 from working.
 
 The other changes are for issues found by automated analysis, a macasp
 typo fix, and two cosmetic fixes for clocks.
