I have this, based on Jason's earlier work. I got side tracked
re-writing the GPIO controller/GPIO interrupt code, so have not posted
it yet.

What i posted should work, but i've effectively thrown the
implementation away and started again in order to get interrupts
working correctly using an irqdomain. The DT description should
however stay the same.
