[ARM] pxa: make GPIO IRQ code less dependent on the internal IRQs
by: 1. introduce dedicated pxa_{mask,unmask}_low_gpio() 2. remove set_irq_chip(IRQ_GPIO_2_x, ...) which has already been initialized in pxa_init_irq() 3. introduce dedicated pxa_init_gpio_set_wake() Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
