[PATCH 3/3] arm64: dts: rockchip: specify pinctrl for i2c adapters on rock-3a

On the Radxa ROCK3 Model A the I2C adapters related to the MIPI DSI
connector and the M.2/NGFF connector use the non-default pins.
Specify the correct pinctrl but leave the adapters disabled (as
they are supposed to be activated by overlays that describe the
external hardware).
