[PATCH 1/3] MIPS: dts: ralink: gardena_smart_gateway_mt7688: use nvmem for EEPROM

[Rosen Penev]

mediatek,mtd-eeprom is a deprecated binding for extracting data on MTD
devices which has been replaced by NVMEM.

The latter is already in wide use with mt76. As this is the only user,
transition to NVMEM.
