[coreboot] Patch for Nokia-IP530, now with working PIRQ table, fix on the pirq_routing

[mbertens]

Signed-off-by: Marc Bertens <mbertens at xs4all.nl>

Part four for the Nokia IP530, This is the patch for hte devcetree.cb
file. Following changes where made;
- Disabled the floppy controller, due to the fact that its not present
on the board.
- Disabled tie parallel port, due to the fact that its not present on
the board.
- taken out the io, irq config of device 7 (PS2 keyb/mouse) it had not
effect anyways, and the controller is not used anyway, but it is
physical present on the board as a 4 pin sil header. 
- Disabled the APCI of the superio, due to the fact that currently no
ACPI is supported by the current configuration of the Nokia IP530.
- Disabled the ACPI device of the southbridge, as above.
- Disabled the UBE device of the southbridge, as it has no connector on
the board.
- Set the ideX_driveY_udma33_enable to 1 to enable the UDMA33 option of
the southbridge (was tested with a 80Gb-WD and a CF 1Gb). 

Remark: currently the CF that i used has the problem with DMA, and
therefor it takes Linux about 120 sec extra to boot. On a asus P4B
(orginal bios) this problem was not encountered. So therefor there must
be something be done extra in coreboot to fix that problem.
