The PORT_1 macro invokes a macro passed as a parameter. Pass the pin
number down to that macro at the bottom of the call stack. This will be
used to compute the pin ranges automatically.

The GPIO driver uses an array of sh_pfc_gpio_pin structures to store
per-GPIO pin data. The array size is miscomputed at allocation time by
using the number of the last pin instead of the number of pins. When the
pin space contains holes this leads to memory overallocation. Fix it.

Fix a compilation error caused by pinconf_generic_parse_dt_config() not
being defined on !CONFIG_OF platforms by guarding the whole DT node
parsing code with #ifdef CONFIG_OF.

Defining a pinconf_generic_parse_dt_config() on !CONFIG_OF would have
been possible as well, but would have resulted in a larger code size on
!CONFIG_OF platforms (such as arch/sh).
