gpio: davinci: fix lazy disable

On a few platforms such as TI's AM69 device, disable_irq() fails to keep
track of the interrupts that happen between disable_irq() and
enable_irq() and those interrupts are missed. Use the ->irq_unmask() and
->irq_mask() methods instead of ->irq_enable() and ->irq_disable() to
correctly keep track of edges when disable_irq is called.

This solves the issue of disable_irq() not working as expected on such
platforms.
