SoC integration of SmartReflex AVS block is varied. Some use
Voltage Processor for a hardware loop in certain OMAP SoC (called
hardware loop), while others have just the AVS block without
hardware loop automatic calibration mechanism for AVS block
to talk through. So provide the Voltage Processor API
to allow for SmartReflex class drivers to use the same.
NOTE: SmartReflex class 3 mode of operation mandates VP APIs
so, refuse to enable AVS driver if corresponding APIs are
not available.
As part of this change, remove the inclusion of voltage.h
which is no longer needed as smartreflex.h includes
linux/platform_data/voltage-omap.h which contain relevant
definitions used here.

There's a couple of these in the patch.
