[PATCH] 2.5.15 IDE 63

- Propagate the queue handling changes to pmac as well.

- Move set_transfer to ide-taskfile.c this is the only place where it's used
   and it can be made static there. Same applies to ide_ata66_check().

- Move ide_auto_reduce_xfer to ide.c.

- Make ide_cmd() local to the only place where it's used. Rename it to
   drive_cmd(). Don't pass drive_cmd_intr() as parameter.

- Remove ide_next command completion type. Nobody is using it.

- Move ide_do_drive_cmd to ide-taskfile. It's used there and in sub-drivers.
   Not in ide.c. The usage inside the device type drivers is entirely bogus
   inconsistent and so on...

- Kill bogus IRQ masking code. The kernel is supposed to handle this properly.
   We should not try to work against possible bugs in the overall irq handling
   code. Wow this is increasing the systems overall responsibility by a
   significant margin.

- Remove disfunctional pdcadma code. It is only misleading to the user.
