pci, pc, pvpanic bug fixes 

This fixes strange pvpanic behaviour: you had to
 pause to let VM continue (and potentially reboot on panic
 if enabled).
 
 This also fixes two bugs reported by Andreas.
 One is a long-standing bug exposed by recent pci changes,
 the other affects old piix machine types and was caused
 by recent acpi changes.
