[PATCH v2 1/2] dt-bindings: mmc: mtk-sd: Document support for Airoha AN7581 SoC

[Christian Marangi]

Add dedicated compatible for Airoha AN7581 SoC integrated MMC controller.
The MMC controller is based on the MT7988 with the difference that it does
have a single clock controlling it.

Add the dedicated compatible to describe the 2 register requirement and
permit to define only 2 clock (the main one and a fixed clock for HS)
