OMAP2+: PRM: add register access functions for VC/VP
On OMAP3+, the voltage controller (VC) and voltage processor (VP) are inside the PRM. Add some PRM helper functions for register access to these module registers. Thanks to Nishanth Menon for finding/fixing a sparse problem. Cc: Nishanth Menon <nm@ti.com> Signed-off-by: Kevin Hilman <khilman@ti.com>
