MFC: r215722

- Fix and enable support for flow control.
- Partially revert r172334; as it turns out the DELAYs in gem_reset_{r,t}x()
  are actually necessary although bus space barriers and gem_bitwait() are
  used, otherwise the controller may trigger an IOMMU errors on at least
  sparc64. This is in line with what Linux and OpenSolaris do.
