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.

Improve IRQ triggering support by making use of the macro
INTC_IRQ_PINS_32() for INTCA on sh73a0. Unfortunately it
is not as easy as just using the macro as-is, we need to
do mask and unmaks in the GIC but configure other bits
and ack in INTCA. Update GPIO IRQ mappings while at it.

This patch adds support for sh73a0 GPIO IRQs by making use
of the PFC GPIO IRQ feature. Only IRQ pins are  supported
at this time. In the future when PINT interrupts also are
supported properly we can easily extend the table with such
information. Also, the sh73a0 is currently making use of
the GIC for external interrupt which is rather unflexible
when it comes to triggering configuration at this point.
