From: Frank Wunderlich <[email protected]>

Add MMC-Support for MT798 SoC

changes in v4:
- drop minitems because of dt_binding_check error
- explain mt7988 compatible with mt7986 platform data in commit description changes in v3:
- use mt7986 platform-data with the mt7988 compatible

changes in v2:
- corrected minItems to require all 4 clocks

Add support for mmc on MT7988 SoC.

We can use mt7986 platform data in driver, but mt7988 needs different clocks so for binding we need own compatible.

changes:
v4:
- explain mt7988 compatible with mt7986 platform data in commit description v3:
- reuse mt7986 platform data instead of copy
