mfd: ezx-pcap: Remvove open coded irq handling
There is no point in checking irq_desc here, as it _is_ available. The driver configured those lines, so they cannot go away. The home brewn disabled/note_interrupt magic can be removed as well by adding a irq_disable callback which avoids the lazy disable. That driver needs to be converted to threaded interrupts.
