2023-02-03efi/cper, cxl: Remove cxl_err.hDan Williams
While going to create include/linux/cxl.h for some cross-subsystem CXL definitions I noticed that include/linux/cxl_err.h was already present. That header has no reason to be global, and it duplicates the RAS Capability Structure definitions in drivers/cxl/cxl.h. A follow-on patch can consider unifying the CXL native error tracing with the CPER error printing. Also fixed up the spec reference as the latest released spec is v3.0.

2022-11-18efi/cper, cxl: Decode CXL Error LogSmita Koralahalli
Print the CXL Error Log field as found in CXL Protocol Error Section. The CXL RAS Capability structure will be reused by OS First Handling and the duplication/appropriate placement will be addressed eventually.

2022-11-18efi/cper, cxl: Decode CXL Protocol Error SectionSmita Koralahalli
Add support for decoding CXL Protocol Error Section as defined in UEFI 2.10 Section N.2.13. Do the section decoding in a new cper_cxl.c file. This new file will be used in the future for more CXL CPERs decode support. Add this to the existing UEFI_CPER config.
