Implement support for pull-up (most pins) and pull-down (EDBGREQ)
handling for the R-Car V2H SoC, using the common R-Car bias handling.
Note that the R-Car V2H Hardware User's Manual Rev. 1.00 says that
the LSI Pin Pull-Up Control Register 11 (PUPR11) controls pull-ups for
the {SCK,WS,SDATA}[01] pins. These are assumed to be typos, as R-Car
V2H has only Serial Sound Interface channels 3 and 4.

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.

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.
