[PATCH 1/2] gpio: mxs: use enable/disable regs to (un)mask irqs

[Sascha Hauer <s.hauer@xxxxxxxxxxxxxx>]

The mxs gpio controller does not only have a mask register to mask
interrupts, but also enable/disable registers. Use the enable/disable
registers rather than the mask register. This does not have any
advantage for now, but makes the next patch simpler.
