dt-bindings: mfd: syscon: Add mediatek,mt8365-infracfg-nao

The register space described by DT node of compatible
mediatek,mt8365-infracfg-nao exposes a variety of unrelated registers,
including registers for controlling bus protection on the MT8365 SoC,
which is used by the power domain controller through a syscon.

Add this compatible to the syscon binding.
