Merge branch 'depends/omap/gpio/runtime-pm-cleanup' into next/cleanup 

Conflicts:
	arch/arm/mach-omap1/gpio16xx.c
	drivers/gpio/gpio-omap.c

Merge in the runtime-pm-cleanup branch from the gpio tree into
next/cleanup, this resolves a nonobvious merge conflict between
the two branches. Both branches move parts of the gpio-omap
driver into platform code, this takes the superset of both
changes.
