By this change, I suggest to remove mmhub/gfxhub_v1_0_ip_funcs and their
IP block, unify them to gmc ip block, this way we cannot lost setting

From hw side, wo won't have real gmc since this chip, mmhub and gfxhub(gc)
instead of it. Maybe we would better to align with hw desgin.
Yeah, I had patches for doing exactly this but then decided dropping it.
What we should do is to have any one implementation of the code handling
both hubs and then have both as separate IP block in the list.
Anyway for now both patches are Reviewed-by: Christian König

I assume that finally fixes S3 on Vega10?
