[v7,1/1] clk: mediatek: remove MT8195 vppsys/0/1 simple_probe

Commit Message

MT8195 VPPSYS0/1 will be probed by the compatible name in
the mtk-mmsys driver and then probe its own clock driver as
a platform driver.

Stephen, could you pick this up for v6.3?  Otherwise we'll end up with
two drivers targeting the same compatible strings.

Thanks

I applied v6 after fixing it by hand.
