These functions are atomic so locking is pointless (noticed by Sergei).
v2:
We can now just use local_irq_save/restore() in qd_testreg() (noticed by Jeff).

* Set hwif->dma_base only if allocation of extra ports succeeds.
While at it:
* Move setting of hwif->dma_{base,master} from ide_{mapped_mmio,iomio}_dma()
to ide_setup_dma().
* Rename 'dma_base' argument to 'base' in ide_setup_dma() (to make the code
obey 80-columns limit and increase its readability).
* Remove stale ide_setup_dma() comment.
v2:
* Change to allocate hwif->dmatable_cpu before reserving I/O ports missed
teardown code (spotted by Sergei). On the second thought this change is
actually unnecessary so revert it in v2.
* Make ide_release_dma_engine() void and remove needless comment.

hwif->hw.io_ports[] and hwif->io_ports[] should be the same but "4drives"
