[PATCH V2] arm64: dts: mediatek: mt7981: add I2C controller

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

MT7981 has one on-SoC I2C controller that differs from recent Mediatek
blocks by having a different SLAVE_ADDR register offset (thus a custom
binding compatible string).

V2: Don't put board-specific clock-div & clock-frequency in the SoC dtsi
    Thanks Angelo!
