All implementations of the .pin_to_portcr() method implement the same
conversion from Port Control Register offset to virtual address. Factor
it out into the two callers.
Remove the pfc parameter, as it is no longer used.
Note that the failure handling in r8a7740_pin_to_portcr() is pro forma,
as the function is never called with an invalid pin number.

The pin control sub-drivers for SH/R-Mobile SoCs contain almost
identical bias handling. The only SoC-specific part is the mapping from
pin numbers to PORTnCR registers.
Reduce code duplication by factoring out the bias handling to the common
pinctrl.c code. Use a callback to handle the pin/register mapping.

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.
