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.

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".

Now, PINMUX_IPSR_MSEL() and PINMUX_IPSR_MODSEL_DATA() are same.

Current PFC driver is very difficult to read, because macro names are
using different length.

	PINMUX_IPSR_NOGP(ispr, ...)
	PINMUX_IPSR_DATA(ipsr, ...)
	PINMUX_IPSR_NOGM(ispr, ...)
	PINMUX_IPSR_NOFN(ipsr, ...)
	PINMUX_IPSR_MSEL(ipsr, ...)
	PINMUX_IPSR_MODSEL_DATA(ipsr, ...)

It can be readable if we can use PINMUX_IPSR_MSEL() instead
of PINMUX_IPSR_MODSEL_DATA()

	PINMUX_IPSR_NOGP(ispr, ...)
	PINMUX_IPSR_DATA(ipsr, ...)
	PINMUX_IPSR_NOGM(ispr, ...)
	PINMUX_IPSR_NOFN(ipsr, ...)
	PINMUX_IPSR_MSEL(ipsr, ...)

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.

The list of functions selected by the MOD_SEL2 register was missing
an entry. This caused all entries after this to modify the MOD_SEL2
register incorrectly.

This bug showed up when selecting i2c2_c pins on the Renesas Hurricane board.

This bug has been present since pinmux support was added for the
r8a7779 SoC by 881023d2 ("sh-pfc: Add
r8a7779 pinmux support") in v3.8-rc4.

The USB_OVCn pins are alternate options for USB over-current detection
when using a 3.3V USB interface. As they're not mandatory they can be
used independently of the USB PENC pins. Don't group the USB_OVCn and
PENC pins to avoid conflicts when the USB_OVCn pins are used by another
function.
