Cadence PCIe core programmed by pcie-cadence*.c. The PCIe controller
will work in both host mode and device mode.
Some of the features of the controller are:
*) Supports both RC mode and EP mode
*) Supports MSI and MSI-X support
*) Supports upto GEN3 speed mode
*) Supports SR-IOV capability
*) Ability to route all transactions via SMMU (support will be added
in a later patch).
