serial: sh-sci: Add support for RZ/V2H(P) SoC
Add serial support for RZ/V2H(P) SoC with earlycon.
The SCIF interface in the Renesas RZ/V2H(P) is similar to that available
in the RZ/G2L (R9A07G044) SoC, with the following differences:
- RZ/V2H(P) SoC has three additional interrupts: one for Tx end/Rx ready
and two for Rx and Tx buffer full, all of which are edge-triggered.
- RZ/V2H(P) supports asynchronous mode, whereas RZ/G2L supports both
synchronous and asynchronous modes.
- There are differences in the configuration of certain registers such
as SCSMR, SCFCR, and SCSPTR between the two SoCs.
To handle these differences on RZ/V2H(P) SoC SCIx_RZV2H_SCIF_REGTYPE
is added.
