Richard Woodruff 0bd4053536 OMAP3: PM: Update clean_l2 to use v7_flush_dcache_all
Analysis in TI kernel with ETM showed that using cache mapped flush
in kernel instead of SO mapped flush cost drops by 65% (3.39mS down
to 1.17mS) for clean_l2 which is used during sleep sequences.
Overall:
	- speed up
	- unfortunately there isn't a good alternative flush method today
	- code reduction and less maintenance and potential bug in
	  unmaintained code

This also fixes the bug with the clean_l2 function usage.
