ARM: gpio: consolidate gpio_to_irq

Many of the gpio_to_irq implementations use the gpiolib version of this function. Provide the standard gpiolib gpio_to_irq() for everyone, but allow platforms to override it if they wish. Add the neccessary overrides for those platforms which do not use the standard definition. Acked-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
