The Renesas Pin Function Controller 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.
Several SoC-specific drivers include core.h, as they need the sh_pfc
structure, which is passed explicitly to the various SoC-specific
callbacks, and used there.
Hence move its definition from core.h to sh_pfc.h, and remove the
inclusion of core.h from all SoC-specific files.

This macro describes a pinmux configuration that needs configuration in
both a Peripheral Function Select Register (IPSR) and in a
GPIO/Peripheral Function Select Register 1 (GPSR). Reflect that in the
macro name for clarity.

This header file will be removed soon.
Copy the helper macro RCAR_GP_PIN(), which is used by the pinctrl
drivers only, to sh_pfc.h, and drop the #include.

The sh_pfc_soc_info.gpio_data[] array contains not only GPIO data, but
also various other pinmux-related data (functions and marks).
Every single driver already calls its local array pinmux_data[].
Hence rename the sh_pfc_soc_info member to "pinmux_data".

Pins with selectable functions but without a GPIO port can't be named
PORT_# or GP_#_#. Add a SH_PFC_PIN_NAMED macro to declare such pins in
the pinmux pins array, naming them with the PIN_ prefix followed by the
pin physical position.
In order to make sure not to register those pins as GPIOs, add a
SH_PFC_PIN_CFG_NO_GPIO pin flag to denote pins without a GPIO port.

The typedef only conceals the real variable type without bringing any
additional value (see Documentation/CodingStyle, section 5.b). Moreover,
it polutes the pinmux namespace. Replace it with the integer type it
used to hide.

pfc-r8a7778 will have many devices pfc support in the future,
and current pfc-r8a7778 is using pin/mux definition macro for SCIF.
The device definition style using macro is readable code IMO,
but creating new macro for each devices is not good sense.
This patch adds common SH_PFC_xx() macro for each new feature devices
