Both hpet and rtc have irq 8 in their ressources, making windows unhappy because of the conflict. Fix this by making rtc check whenever the hpet is present, and claim irq 8 only in case it isn't. So rtc gets irq 8 only in case you start qemu with the -no-hpet switch.
Verified working in both linux (check pnp boot messages) and windows (check rtc ressources in device manager) guests.
Resolves the Windows 7 RTC resource conflict on Q35 as well.
However, Windows XP continues to blue screen on boot as I reported, and Brad also posted (for both piix and q35).
Looks like a regression caused by d9f5cdbdf55d61aef9a1a534d9123ef734427478 - I'll revert that patch if no fix is found.
