Move structure containing PMIC configurable settings into struct
voltagedomain.  In the process, rename from omap_volt_pmic_info to
omap_voltdm_pmic (_info suffix is not helpful.)

No functional changes.

Convert VC/VP register access to use PRM VC/VP accessor functions.  In
the process, move the read/write function pointers from vdd_info into
struct voltagedomain.

No functional changes.

Additional cleanup:
- remove prm_mod field from  VC/VP data structures, the PRM register
  access functions know which PRM module to use.

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.
