To: edk2-devel, ryan.harkin; +Cc: leif.lindholm, Ard Biesheuvel
Replace the open coded reimplementation of 'PCI emulation' with a pair
of calls into NonDiscoverableDeviceRegistrationLib to register the OHCI
and EHCI controllers. These will be picked up by the generic driver instead.

To: edk2-devel, ryan.harkin; +Cc: leif.lindholm, Ard Biesheuvel
In order to be able to switch to the generic PCI host bridge driver,
implement the glue library that exposes the PCIe parameters to the
common driver. Since the Juno performs some initialization of the
PCIe control registers as well, copy that code in the library's
constructor.
