Patches 1-4:
Fix tests so that devices do not use non-zero slots on the pcie root
ports. PCIE ports only have one slot, so PCIE devices can only be
plugged into slot 0 on a PCIE port.

Patch 5:
Enforce only one slot on PCIE port.

Patch 6: add a cosmetic comment addition for better clarity of the code.

The test fixes must be applied before the QEMU change that checks for use
of a single slot in PCIE port.
