Alan Cox d43744390e pata_cmd64x: implement serialization as per notes
Daniela Engert pointed out that there are some implementation notes for the
643 and 646 that deal with certain serialization rules. In theory we don't
need them because they apply when the motherboard decides not to retry PCI
requests for long enough and the chip is busy doing a DMA transfer on the
other channel.

The rule basically is "don't touch the taskfile of the other channel while
a DMA is in progress". To implement that we need to

- not issue a command on a channel when there is a DMA command queued
- not issue a DMA command on a channel when there are PIO commands queued
- use the alternative access to the interrupt source so that we do not
  touch altstatus or status on shared IRQ.

Updated to remote extra conditional check Bartlomiej noted and to remove
the variables for irq checks as the CMD648 doesn't have the underlying problem.
