On some platforms (such as Spreadtrum platform), the GPIO keys can only
be triggered by level type.

How do you stop the interrupt from re-triggering as long as the key
stays pressed?

We will set the level type irq handler as handle_level_irq(), in this
function, it will mask and ack the irq firstly.
