Extend the existing driver to support the SCIF serial ports on the Renesas RZ/G2L (R9A07G044) SoC. This also requires us to ensure that the relevant reset signal is de-asserted before we try to talk to the SCIF module.

v1->v2:
- Moved handle_error() changes out to a separate patch earlier in the series.
- Unconditionally de-assert the module reset during probe.

Please keep the list sorted.
