- cs5530 patches by Adam J. Richter. Small indent style adjustments.

 - qd65xx cli()/sti() adjustments.

 - Fix bogous command in ide.c pointed out by Peter Vendroviec.

 - Eliminate ide_stall_queue(). For those worried: we didn't sleep at
   all.

 - Eliminate support for "sector remapping". loop devices can handle
   stuff like that. All the custom DOS high system memmory loaded
   BIOS workaround tricks are obsolete right now. If anywhere it should
   be the FAT filesystem code which should be clever enough to deal with
   it by adjusting it's read/write methods.

 - PCI "scather gather" allocation handling revamp by Adam J. Richter.

 - Simplify do_ide_request after ->sleep removal.

 - Make do_ide_request prefer to handle the device matching the request
   queue it was called for first. RQ-queues are unique for devices.
   In a next step queuedata will be changed to point to the device
   not the channel.
