GPIO (PINCTRL) block is identical on Renesas RZ/G2L, RZ/G2UL and RZ/V2L
SoC's, so instead of selecting PINCTRL_RZG2L config for each SoC select
PINCTRL_RZG2L config option if ARCH_RZG2L is enabled. The ARCH_RZG2L
config option is already selected by ARCH_R9A07G043, ARCH_R9A07G044 and
ARCH_R9A07G054.

RZ/G2UL SoC has fewer pins compared to RZ/G2L and the port pin
definitions are different compared to RZ/G2L.
This patch adds a new compatible to take care of these differences by
adding r9a07g043_data with r9a07g043_gpio_configs and
rzg2l_dedicated_pins.common.

Most, but not all, Renesas pin control drivers use the "sh-pfc" pin
control framework. As of commit 8449bfa9e6a9f7ec ("pinctrl: sh-pfc:
Collect Renesas related CONFIGs in one place"), the code for this
framework is always built when Renesas SoC pin control support is
enabled, regardless of whether the enabled pin control drivers need it
or not.
Fix this by reintroducing the CONFIG_SH_PFC symbol to control inclusion
of the "sh-pfc" framework and its dependencies, and selecting it when
needed.
This reduces kernel size of a typical RZ/A1 or RZ/A2 kernel by more than
6 resp. 11 KiB.

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.
