[PATCH 3/5] arm64: dts: imx8mq-phanbell: Enable i2c2 and i2c3

[Rudi Heitbaum]

i2c2 is brought out on the 40-pin expansion header. i2c3 carries the
board's audio codec and also reaches the header.

Both run at 100 kHz, which is what the vendor devicetree uses. i2c1 is
internal to the board and carries only the PMIC, which is why it is the one
already at 400 kHz.
