Implement support for pull-up (most pins) and pull-down (ASEBRK#/ACK)
handling for R-Car M2-W and M2-N, and RZ/G1M and RZ/G1N SoCs, using the
common R-Car bias handling.
Note that on RZ/G1 SoCs, the "ASEBRK#/ACK" pin is called "ACK", but the
code doesn't handle that naming difference. Hence users should use the
R-Car naming in DTS files.

This driver supports both RZ/G1[MN] and R-Car M2-W/M2-N SoCs.
Optimize pinctrl image size for RZ/G1[MN], when support for R-Car
M2-W/M2-N (R8A779[13]) is not enabled.

The drivers/pinctrl/sh-pfc subdirectory was originally created to group
pin control drivers for various Renesas SuperH and SH-Mobile platforms.
However, the name "sh-pfc" no longer reflects its contents, as the
directory now contains pin control drivers for Renesas SuperH, ARM32,
and ARM64 SoCs.
Hence rename the subdirectory from drivers/pinctrl/sh-pfc to
drivers/pinctrl/renesas, and the related Kconfig symbol from
PINCTRL_SH_PFC to PINCTRL_RENESAS.
Rename the git branch in MAINTAINERS, too, for consistency.
