[ARM] 4988/1: Add GPIO lib support to the EP93xx
Adds support for the generic GPIO lib to the EP93xx family. The gpio handling code has been moved from core.c to a new file called gpio.c. The GPIO based IRQ code has not been changed. Signed-off-by: Ryan Mallon <ryan@bluewatersys.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
