Introduce a new EP core layer in order to support endpoint functions
in linux kernel. This comprises of EPC library
(Endpoint Controller Library) and EPF library (Endpoint
Function Library). EPC library implements functions that is specific
to an endpoint controller and EPF library implements functions
that is specific to an endpoint function.

Any special reason to include pci/endpoint and pci/dwc in drivers/Makefile
instead of being inside pci/Makefile? pci/host is still inside pci/Makefile.

CONFIG_PCI enables all the pcie host support. Endpoint support should be
enabled independent of the host support. Moving pci/endpoint inside
pci/Makefile will build endpoint support only if CONFIG_PCI is enabled. For the
same reason kept pci/dwc in drivers/Makefile since dwc drivers can be used
either in host mode or device mode (or both).

Good point! Very well.
