Remove the use and definition of the NR_GPIO_IRQS macro for
device tree targets. This involves removing the macro from the
gpio driver as well. Since this a common gpio driver, certain
non-device tree targets had to be fixed to support this.
However, the NR_GPIO_IRQS macro continues to exist for the
non-device tree targets.
