533743dccb sh-pfc: Replace pinmux_enum_id typedef with u16 
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.

b9ffcc2b12 pinctrl: sh-pfc: r8a7779: Fix missing MOD_SEL2 entry 
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 881023d28b ("sh-pfc: Add
r8a7779 pinmux support") in v3.8-rc4.

350753bf2b sh-pfc: r8a7779: Don't group USB OVC and PENC pins 
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.

caa5bac3b4 sh-pfc: Replace SoC info data and mark ranges with a number of pins 
The data and mark ranges are only used to check whether a GPIO
corresponds to a real pin or a function. As pins come first in the list
of GPIOs and in the platform-specific GPIO enumerations, we can replace
the data and mark ranges by a number of pins.

Add an nr_pins field to struct sh_pfc_soc_info to store the number of
pins implemented by the SoC, remove the data and mark range fields and
introduce sh_pfc_gpio_is_pin() and sh_pfc_gpio_is_function() functions
to replace range-based checks.
