Add pins, groups, and functions for the SPI Multi I/O Bus Controller
(RPC-IF) to the R8A77990 PFC driver. They are to be used when an
Octal-SPI Flash or HyperFlash is connected.
Redefine the QSPI[01] pin groups using the RPC DQ[0:7] pin data, to save
memory.

According to R-Car Gen3 HW documentation 2.20 onwards, drive-strength is
introduced to r8a77990. It is also documented for r8a774c0. Add it to
the pinctrl driver.

The pfc parameter of the .pin_to_pocctrl() method was never used.
It is a relic of the old I/O voltage handling before commit
8775306dcf48092f ("pinctrl: sh-pfc: refactor voltage setting").
Remove the parameter, as it prevents the checker from calling this
function for validating consistency of the pin control tables.

The VIN_DATA_PIN_GROUP() macro and vin_data{12,16,} unions are used to
define multiple VIN data groups with different numbers of lanes, while
referring to a single array of data pins, thus saving memory.
However, the same feature would be useful for other resizable buses,
like MMC, SDHI, QSPI, LCD, BSC, ...
Rework the mechanism for generic use:
- Use the new SH_PFC_PIN_GROUP_SUBSET() helper to remove the need for
bus-specific unions,
- Rename VIN_DATA_PIN_GROUP() to BUS_DATA_PIN_GROUP(),
- Rename the macro parameters to better reflect their purposes,
- Move the macro up, where it belongs.
Update all individual pin control drivers for the above changes.

Some instances of struct sh_pfc_soc_operations are called
"<soc>_pfc_ops", others are called "<soc>_pinmux_ops" or just
"pinmux_ops". Settle on the first variant, to avoid confusion with
"struct pinmux_ops" in the pinctrl core, and to increase consistency.

The Renesas Pin Function Controller driver uses two header files:
- sh_pfc.h, for use by both core code and SoC-specific drivers,
- core.h, for internal use by the core code only.
Hence move the R-Car bias helper declarations from core.h to sh_pfc.h,
and drop the inclusion of core.h from SoC-specific drivers that no
longer need it.

This driver supports both RZ/G2E and R-Car E3 SoCs.
Optimize pinctrl image size for RZ/G2E, when support for R-Car E3
(R8A77990) 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.
