Hi All,

This patch series adds a couple of fixes for rpc-if driver and
adds support for RZ/G2L SoC, where the SPI Multi I/O Bus Controller
is identical to the RPC-IF block found on R-Car Gen3 SoC's.

Note: patch applies on top of [1].

I did some basic testing on the Falcon board with a Renesas R-Car V3U
SoC and did not find a regression, so:

Thank you for testing this, I will include the Tested-by tag along
with the RB tags.
