b58e5fac96 ARM: shmobile: sh73a0: Support sparse GPIO numbers
The SH73A0 SoC has sparse GPIO numbers. Declare the pin numbers ranges
in the PFC SoC data and use the pin numbers in the GPIO API.

c07f54f604 sh-pfc: Look up IRQ table entries by GPIO number
Instead of converting the GPIO number to an enum_id and looking up IRQ
table entries by enum_id, replace the pinmux_irq enum_ids field with a
gpios field and lookup entries using the GPIO number.

a373ed0aa2 sh-pfc: Split pins and functions definition tables
Split the GPIOs table into a pins table for real GPIOs and a functions
table for function GPIOs.

Only register pins with the pinctrl core. The function GPIOs remain
accessible as GPIOs.

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.

d7a7ca5781 sh-pfc: Replace first_gpio and last_gpio with nr_gpios
The SoC information first_gpio field is always equal to 0, and the
last_gpio field is the index of the last entry in the pinmux_gpios
array. Replace the first_gpio and last_gpio fields by a nr_gpios field,
and initialize it to ARRAY_SIZE(pinmux_gpios).
