Merge branch 'omap/cleanup-prcm-part2' into next/dt

This resolves a nontrivial conflict where the omap_prcm_restart
is removed in one branch but another use is added in another
branch.

Conflicts:
	arch/arm/mach-omap2/cm33xx.c
	arch/arm/mach-omap2/io.c
	arch/arm/mach-omap2/prm_common.c

-         * 1. enable self-refresh on idle request

-         * if HW warm reset is the source, apply below steps before any

-         * 1. Reset SMS and SDRC and wait till reset is complete
