irqdomain: Support three-cell scheme interrupts
Add new function *_twothreecell() to extend support to parse three-cell
interrupts which encoded as <instance hwirq irqflag>, the translate
function will retrieve irq number and flag from last two cells.
This API will be used in gpio irq driver which need to work with
two or three cells cases.
