The J721E PCIe is hardware specific to TI SoC parts so add a dependency
on that so it's available for those SoC parts and for compile testing but
not necessarily everyone who enables the Cadence PCIe controller.

Use "PCIe controller" consistently instead of "host bridge", "bus driver",
etc. Annotate with "(host mode)" or "(endpoint mode)" as needed.

Add support for PCIe controller in J721E SoC. The controller uses the
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).

Cadence core library files may be used by various platform drivers.
Add a new directory "cadence" to group all the Cadence core library files
and the platforms using Cadence core library.
