2009-03-31ide: be able to build pmac driver without IDE built-inGilles Espinasse

2009-03-31ide-pmac: IDE cable detection on Apple PowerBookTOMARI Hisanobu
As IDE cable used on Apple PowerBook/iBook laptops are always of "Short 40" type when the firmware says it's 80 conductor one, the cable detection should return ATA_CBL_PATA40_SHORT on those machines. This enables to automatically use UDMA5 even with drives that doesn't correctly detect those cables on Apple laptops.

2009-03-31ide: rename IDE_TFLAG_IN_[HOB_]FEATURESergei Shtylyov
The feature register has never been readable -- when its location is read, one gets the error register value; hence rename IDE_TFLAG_IN_[HOB_]FEATURE into IDE_TFLAG_IN_[HOB_]ERROR and introduce the 'hob_error' field into the 'struct ide_taskfile' (despite the error register not really depending on the HOB bit).

Add support for the CompactFlash specific PIO modes 5/6 and MWDMA modes 3/4.
