[PATCH] 2.5.14 IDE 55

 - Update HPT374 driver carried over from 2.4.xx series by Andrew Morton.
   Resync it with the recent host chip driver changes, or better the
   introduction of an API at all.

 - Consolidate the handling of device ID byte order in one place.
   This was spotted and patched by Bartomiej onierkiewicz.

 - Eliminate CONFIG_BLK_DEV_IDEPCI - it's duplicating the functionality of the
   already present and fine CONFIG_PCI flag and if we are a PCI host, we are
   indeed very likely to need host chip support anyway.

 - Remove some redundant info about the model and channel number from
   /proc/ide. Remove the binary entries not helpful to the user, and not used
   by any program and redundant to corresponding ioctls.

 - Properly return udma_read and udma_write values in taskfile.

 - Only initialize XXX_udma to the default handlers if it has not been
   initialized by the host chip initialization.

I have enabled spin lock debugging and can see that on device
flush the spin locks get wrong counts... no problems elsewher ethus
far. I will re check them next time around.
