arm64: dts: ti: k3-j721e: Rename mux header and update macro names

[ Upstream commit c65176fd49f45bd5a5ffaa1790109745d1fa462c ]

We intend to use one header file for SERDES MUX for all
TI SoCs so rename the header file.

The exsting macros are too generic. Prefix them with SoC name.

While at that, add the missing configurations for completeness.
