Notes:
Changes since v7:
- remove unused gpu_reservde memory range
- get rid of duplicate ethernet clock assignments
Changes since v6:
- rename mdio0->mdio
Changes since v5:
- cleanup dt_bindings_check warnings
Changes since v4:
- cleanup usage of "status = okay|disabled"
- fix remaining non-generic node names
- rework sai nodes to not duplicate the existing settings in stm32mp151.dtsi
Changes since v3:
- cleanup board-compatible
- cleanup aliases
- rename nodes according to schema
- use interrupt flag
