m68k/q40: Replace q40ide driver with pata_falcon and falconide
This allows m68k q40 systems to switch from the deprecated IDE subsystem to libata. Enhance the byte-swapping falconide and pata_falcon platform drivers to accept an irq resource, for use on q40. Atari ST-DMA IRQ arrangements seem to co-exist with q40 IRQ arrangements without too much mess. The new IO resources were added solely for the purpose of making request_region() reservations identical to those made by q40ide: these regions aren't used for actual IO.
