So VPPSYS0 and VPPSYS1 aren't dependant on MMSYS anymore?

Like this, it doesn't look like this will ever work fine, so if you want
that to happen, you must provide a good explanation, and then, since MT8188
and MT8195's VPPSYS are practically the same, you should also convert MT8195
to do the same, and make sure that everything works as expected before sending
a commit upstream.

Please, explain.

Thanks,
Angelo
