arm64: dts: ti: k3-am67a-beagley-ai: Setup I2C for CSI/DSI connectors

Browse Source 
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.
