On OMAP4, gpio_irq_handler can be chained to a physical interrupt using
the GIC as the primary IRQ chip. Now that the GIC uses the fasteoi flow
model, the chained handler must invoke ->irq_eoi once handling is
complete.

This patch adds a conditional call to ->irq_eoi in the GPIO IRQ handler
for OMAP platforms. For OMAP implementations using other primary
interrupt controllers, the ->irq_ack call remains and is also made
conditional on the support offered by the controller.
