Rather than expose the VP functions directly, how about adding a new API
at the voltdm layer to start/stop AVS. Maybe something like:
voltdm_avs_start(struct voltagedomain *voltdm)
voltdm_avs_stop(struct voltagedomain *voltdm)
These will internally just call VP enable/disable for now, but we may
have more to add to these in the future to support other SR classes.
