Log:
MFC: r233421
Given that this is a host-PCI-Express bridge driver, create the parent
DMA tag with a 4 GB boundary as required by PCI-Express. With r232403
(MFC'ed to stable/8 in r233394) in place this actually is redundant.
However, the host-PCI-Express bridge driver is the more appropriate
place for implementing this restriction.
