[PATCH v2 1/2] arm64: dts: mediatek: mt8395-radxa-nio-12l: Drop redundant i2c2 drive-strength

[Ricardo Pardini via B4 Relay]

From: Ricardo Pardini <ricardo at pardini.net>

The i2c2_pins node specifies both drive-strength (mA, standard driving)
and drive-strength-microamp (uA, advanced driving). These are mutually
exclusive: the generic pinconf parser logs "cannot have multiple drive
strength properties" at boot, and on MediaTek the advanced driving enable
bit makes the uA value authoritative, leaving the mA value dead.

Drop the redundant drive-strength, keeping only drive-strength-microamp,
matching i2c4_pins.
