discovered with IOAPIC disabled.

The problem was that drivers/serial/8250_acpi.c found COM1 in the ACPI
namespace and called acpi_register_gsi() to set up its IRQ.  ACPI tells us
that the COM1 IRQ is edge triggered, active high, but acpi_register_gsi()
was ignoring the edge_level argument, so it blindly set the COM1 IRQ to be
level-triggered.

I noticed that insert_resource() incorrectly handles the case of an
existing parent resource with the same ending address as a newly added
child.  This results in incorrect nesting, like the following:

	# cat /proc/ioports
	<snip>
	002f0000-002fffff : PCI Bus #48
	  00200000-002fffff : /pci@800000020000003
	</snip>

Make sure that number of sectors != 0 for in/out command before sending
it to drive.  Remove no longer needed checks from flagged_* PIO handlers.

PIO handlers under CONFIG_IDE_TASKFILE_IO=n are never used for bio
based requests (rq->bio is always NULL) so we can use rq->buffer
directly instead of calling ide_[un]map_buffer().

These handlers are nowadays used only for REQ_DRIVE_TASKFILE
requests (rq->bio is always NULL) which aren't retried et all so
remove code 'rewinding' rq->current_nr_sectors and some FIXMEs.

If REQ_DRIVE_* request fails ide_end_drive_cmd() should be called

'cat /proc/ide/hdx/identify' generates REQ_DRIVE_TASKFILE request
(for WIN_PIDENTIFY command) even for devices controlled by ide-cd.
All other drivers don't try to retry such requests.

The IDE sparse fixups cause 2 warnings (unused variables `val' and
`reg') on m68k and APUS.  However, the reason why this code was
commented out is gone.  So just remove the special case.

They are only included from these drivers.

- add DECLARE_CS_DEV() (cs5520)
- remove duplicate DISPLAY_SC1200_TIMINGS define (sc1200)
- remove unused SIIMAGE_BUFFERED_TASKFILE, SII_DEBUG
