OMAP7XX: Clocks: Add omap850 support

Browse Source 
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. Initial clock support was done in
the Linwizard tree by Zebediah C. McClure.
