Add power domain binding to the mediatek DPI controller
for MT8186.
Also, add power domain binding for other SoCs like
MT6795 and MT8173 that already had power domain property.

I was a bit confused here.

Can we add something like this?
if:
   not:
        (mt6795, mt8173, mt8186)
then:
     properties:
         power-domains: false

Thanks,
Rohit.
