Subject: [PATCH v2 1/1] arm64: dts: mt8192: Add mmc device nodes

In mt8192 SoC, mmc driver dose not use the MSDC module to control
clock. It will read/write register to enable/disable clock. Also
there is no other device of mt8192 using MSDC controller.

We add mmc nodes for mt8192 SoC and remove the clock-controller in
dts for avoid a duplicate unit-address(11f60000) warning.
