Implement support for pull-up (most pins) and pull-down (ASEBRK#/ACK)
handling for R-Car H2 and RZ/G1H SoCs, using the common R-Car bias
handling.
Note that on RZ/G1H, 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/G1H and R-Car H2 SoCs.
Optimize pinctrl image size for RZ/G1H, when support for R-Car H2
(R8A7790) is not enabled.

and VIN2-G8.

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.
