i.MX: Fix GPIO ISR register write 



Writing the ISR register is supposed to clear interrupt status bits,
not to set them.

This patch makes '-M sabrelite' work without devicetree changes (Linux
kernel versions 3.18 to 4.7 with imx_v6_v7_defconfig and up to v4.8 with
multi_v7_defconfig; mainline has different problems).
