Fix buggy assertion in pcid capability parser.
...
The pcid capability parsing code has an assertion that checks for dword
alignment. Unfortunately, the check was previously checking for
alignment to qwords. This fixes that.
I found this issue by using qemu to emulate adding different pci
devices. I managed to come across a device that had a capability
aligned on dword, but not qword. That exposed the bug.

Fixed PCI bus scan to scan bus 0xFF.
...
Previously, the PCI bus scan was skipping bus 0xFF. Now it does not.
I used a match expression to make sure that all cases are accounted for.
I also changed the PCI dev scan and PCI func scan to use a match
expression in a similar way to make sure all cases are account. While
this is functionally the same as before, the match expression will not
allow unhandled cases and should be easier to read and make it harder
to introduce bugs.
