Pull up following revision(s) (requested by msaitoh in ticket #37):

        doc/3RDPARTY: revision 1.1641
        sys/dev/pci/if_ena.c: revision 1.16
        sys/arch/amd64/conf/GENERIC: revision 1.532

If the memory space's BAR and the MSI-X table is on the same BAR,
reserve the space. Almost the same as nvme_pci.c and xhci_pci.c.
Tested by ryoon@.

Add ena(4).
