rtc: rzn1: Add support for Renesas RZ/T2H and RZ/N2H SoCs

Add support for the RTC block found on the Renesas RZ/T2H (R9A09G077)
and RZ/N2H (R9A09G087) SoCs.

These SoCs integrate a closely related variant of the RZ/N1 RTC IP, but
do not implement the RTCA0SUBU register. Use variant-specific match data
to disable SUBU support for these SoCs.
