[PATCH v4 1/2] dt-bindings: mmc: mmc-slot: Make compatible property optional

[Dharma Balasubiramani]

The compatible property is required for some vendor-specific device trees,
such as Amlogic's meson-mx-sdio, but is unnecessary for others, like
Microchip's DTS. To resolve unintended warnings for configurations that do
not require it, remove compatible from the required properties in
mmc-slot.yaml.

Since meson-mx-sdio still requires compatible, explicitly add it to its
required list in amlogic,meson-mx-sdio.yaml.
