Subject: [PATCH V2 03/14] arm64: dts: ti: k3-j721e-beagleboneai64: Move camera gpio pinctrl to gpio node

Move the GPIO mux configuration needed for camera module to work to the
GPIO node instead of the I2C node.

Camera nodes are maintained as overlay files, but the common mux is
always needed to ensure that camera probes fine and ensuring the mux
is configured as part of the GPIO module allows for the multiple
overlay files to be simpler.
