bindings: arm: fsl: Add PHYTEC phyBOARD-Nash-i.MX93 board

Add devicetree bindings for PHYTEC phyBOARD-Nash-i.MX93 board based on
the existing PHYTEC phyCORE-i.MX93 SoM (System-on-Module).

Adjust the compatibles for the existing phyBOARD-Segin-i.MX93 board, to
be able to add additional board based on the phyCORE-i.MX93 SoM.
