We now have a way for PCIe devices to force iommu.strict through the
"struct device" and that's now hooked up. Let's remove the special
case for PCIe devices.
NOTE: there are still other places in this file that make decisions
based on the PCIe "untrusted" status. This patch only handles removing
the one related to iommu.strict. Removing the other cases is left as
an exercise to the reader.
