The omap_gpio_irq_type() can do only configuration of GPIO IRQ
triggering type, because now OMAP GPIO driver has implemented
.irq_startup()/.irq_shutdown() which are responsible for
GPIO bank enabling and pin direction configuration.
Hence, remove redundant code and omap_gpio_init_irq() which is
not used any more.
