MdePkg: Add PCIe capability structures for DPC and DLF
Add definitions for Downstream Port Containment (DPC) Extended Capability. Add definitions for Data Link Feature (DLF). Update existing definitions for Precision Time Measurement (PTM) and move it from PciExpress40.h to PciExpress31.h as it was defined in 3.1. Mark some duplicate symbols 'obsolete' to remove in future. Signed-off-by: Jacek Kolakowski <[email protected]>
