The following patch series adds xHCI support for the Broadcom 2711 SoC used
on the Raspberry Pi 4 by:

* Adding the relevant constants to the Silicon header files

* Adding the segment library required to handle the nonstandrd ECAM that the
  SoC uses. Basically, in the Bcm2711, root port is the first bytes of the
  register space (offset 0) and individual devices are selected by computing
  their BDF index and writing that into the CFG_INDEX register before ECAM
  data can then be read/written at CFG_DATA.

* Adding the Host Bridge Library

* Adding PCIe and xHCI support into the platform using the recently introduced
  NonCoherentIoMmuDxe.

Once this series has been applied, the 4 USB ports of the platform can be used
within the UEFI environment.
