gpio: ep93xx: Fix port F hwirq numbers in handler

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Fix wrong translation of irq numbers in port F handler, as ep93xx hwirqs
increased by 1, we should simply decrease them by 1 in translation.
