dt-bindings: timer: renesas,rz-mtu3: document RZ/{T2H,N2H}
Compared to the previously supported SoCs, the Renesas RZ/T2H and RZ/N2H
SoCs do not have a reset line.
Add support for them by moving the required reset into a conditional
matching all compatibles for the existing SoCs. Disable the resets for
RZ/T2H and RZ/N2H.
Document RZ/T2H and RZ/N2H, and use the generic compatible as a
fallback, as functionality is the same.
