Compared to the previously supported SoCs, the Renesas RZ/T2H and RZ/N2H
SoCs do not have a reset line.

Add a new conditional only matching RZ/T2H and RZ/N2H which disables the
resets property.

Document RZ/T2H and RZ/N2H, and use the generic compatible as a
fallback, as functionality is the same.
