arm64: dts: microchip: sparx5_pcb134: add missing I2C mux unit addresses

The children of I2C mux should be named "i2c", according to DT schema
and bindings, and they should have unit address.

This fixes dtbs_check warnings like:

  sparx5_pcb134_emmc.dtb: i2c0-imux@0: Unevaluated properties are not allowed ('#address-cells', '#size-cells', 'i2c_sfp1', ...

and dtc W=1 warnings:

  sparx5_pcb134_board.dtsi:548.23-555.4: Warning (simple_bus_reg): /axi@600000000/sfp-eth12: missing or empty reg/ranges property
