drm/msm/a6xx: Share dependency vote table with GMU

Browse source

A8x GMU firmwares expect a separate vote table which describes the
relationship between the Gx rail and MxA rail (and possibly Cx rail).
Create this new vote table and implement the new HFI message which
allows passing vote tables to send this data to GMU.
