pci: Remove PCI_CAPABILITY_CONFIG_*
Half of these aren't used anywhere, the other half are wrong. Now that
device assignment is trying to match physical hardware offsets for PCI
capabilities, we can't round up the MSI and MSI-X length. MSI-X is
always 12 bytes. MSI is variable length depending on features, but for
the current device assignment implementation, it's always the minimum
length of 10 bytes.
