[ARM] 2836/1: Cleanup IXP4xx GPIO code

Browse Source 
Patch from Deepak Saxena

This patch implements the set_irq_type() hooks for configuring GPIO
IRQ type and updates all the platforms to use it instead of the
gpio_line_config() function which is now used to configure input
vs. output on the pins.
