I've noticed the mtk-sd binding needs a bit more work get into a more
clean state.

There are 2 properties missing that maybe need to be added later or
dropped from devicetrees:
drv-type (which is used in mt8183-kukui.dtsi and set to <2>)
and
r_smpl (used in mt7622-rfb1.dts and mt7622-bananapi-bpi-r64.dts, both
times set to <1>)

i don't know their function and boundaries and i do not find them in
driver. I guess they are added by accident, so i removing them in the
patches 5+6.

v2:
- add compatible based binding
v3:
- solve "not" statement in binding and reorder if statements,drop mt8183
- added patches removing invalid properties (not in driver)

Please drop my tag, so I will re-review it.

Thanks!
