MdePkg/Include/IndustryStandard: CXL 1.1 Registers
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2611 Register definitions from chapter 7 of Compute Express Link Specification Revision 1.1 are ported into the new Cxl11.h. The CXL Flex Bus registers are based on the PCIe Extended Capability DVSEC structure header, led to the inclusion of upgraded Pci.h.
