Update ide/ppc/pmac.c

Hi Marcelo !

This patch against 2.4.21-rc3 will update drivers/ide/ppc/pmac.c to the latest version in my 2.4.21 tree. It makes use of the "hold" field you added to hwif in -rc3 to avoid a problem with ide-cs, fix the DMA routines for proper usage of the new ide_exectute_command(), and remove a now useless delay (since ide-probe.c now contains the wait for BSY, the delay is no longer useful), and finally, allow the new "Kauai" ATA/100 interfaces to be probed before the old ones so the internal HD of those machines becomes hda and not hde

Please apply before your release 2.4.21 final,

Ben.
