openpic: fix CTPR and de-assertion of interrupts
Properly implement level-triggered interrupts by withdrawing an
interrupt from the raised queue if the interrupt source de-asserts.
Also withdraw from the raised queue if the interrupt becomes masked.
When CTPR is written, check whether we need to raise or lower the
interrupt output.
