PCI: Make the intel-iommu_wait_op macro work when jiffies are not running
The following patch changes the intel-iommu.c code to use the TSC
instead of jiffies for detecting bad DMAR functionality. Some systems
with bad bios's have been seen to hang in early boot spinning in the
IOMMU_WAIT_IO macro. This patch will replace the infinite loop with a call to
panic.
