Legacy Windows operating systems like Windows XP and Windows 2003
require _DIS method to be present for all interrupt links.
PC machines already have a no-op implemented for GSI links, add
it also in Q35.

Hi,
I tested this patch with WinXP and Win 2003, but also with Win 10, and Fedora.
This solves a BSOD early in the setup process.
WinXP/2003 can be tested using:
-device piix3-ide,id=legacyide \
-drive file=winxp-q35.qcow2,if=none,id=disk -device
ide-hd,drive=disk,bus=legacyide.0 \
-drive file=xp_sp3.iso,if=none,id=cdrom -device
ide-cd,drive=cdrom,bus=legacyide.1
Please note that you have to use the piix3-ide because Win2003 (and probably XP)
does not have Q35 AHCI drivers inbox.
Thanks,
Marcel
