OMAP7XX: PM: Add omap850 support

This patch is part of a series which unifies all duplicated code between
omap730 and omap850. All cpu checks are converted to cpu_is_omap7xx() and
CONFIG_ARCH_OMAP850 is added to all CONFIG_ARCH_OMAP730 checks.

This file had no omap850 specific code. Original omap850 support in Linwizard
was done by cloning the omap730 code. That work was done by Zebediah C. McClure.
