gpio: msm: Fix irq mask/unmask by writing bits instead of numbers
commit 4cc629b7a20945ce35628179180329b6bc9e552b upstream.
We should be writing bits here but instead we're writing the
numbers that correspond to the bits we want to write. Fix it by
wrapping the numbers in the BIT() macro. This fixes gpios acting
as interrupts.
