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.
