dt-bindings: i3c: silvaco,i3c-master: add i.MX94 and i.MX95 I3C 



Add compatible string "nxp,imx94-i3c" and "nxp,imx95-i3c" for the i.MX94
chip and i.MX95 chip. Backward is compatible with "silvaco,i3c-master-v1".

Also i.MX94 and i.MX95 I3C only need two clocks and Legacy I3C needs
three clocks. So add restrictions for clock and clock-names properties
for different Socs.
