[PATCH v3 1/4] arm64: dts: ti: k3-am67a-beagley-ai: Setup I2C for CSI/DSI connectors

[Jai Luthra]

I2C0 is used by the 22-pin CSI1/DSI0 connector and I2C2 is used by the
22-pin CSI0 connector.

Add the missing pinmux definition for the I2C2, and setup both nodes but
keep them disabled. They will be enabled by the camera and display
overlays.

Changes in v3:
- Also add disabled nodes for I2C0 and I2C2
- Earlier this commit was only adding pinctrl for I2C2, so update the
  commit message accordingly
