Replace the VP tranxdone check/clear with helper functions from the
PRM layer.
In the process, remove prm_irqst_* voltage structure fields for IRQ
status checking which are no longer needed.
Since these reads/writes of the IRQ status bits were the only PRM
accesses that were not to VC/VP registers, this allows the rest of the
register accesses in the VC/VP code to use VC/VP specific register
access functions (done in the following patch.)

This patch is primarily a move of VP specific code from voltage.c into
its own code in vp.c and adds prototypes to vp.h
No functional changes, except debugfs...
VP debugfs moved to 'vp' subdir of <debugfs>/voltage/ and 'vp_'
prefixes removed from all debugfs filenames.
