BACKPORT: FROMLIST: soc: mediatek: add mmsys support for MT8196

1. Defining driver data and adding compatible string
for different subsystems
(DISPSYS0, DISPSYS1, OVLSYS0, OVLSYS1, VDISP_AO)
2. Adding functions to control top clocks and ddp clocks.
3. Updating the probe function to initialize clocks and
enable runtime PM if its node has the power-domains property.
4. Adding functions to configure ddp components and
set default configurations.
5. Adding the routing table for each mmsys in MT8196.
