The current cxl region size only indicates the size of the CXL memory region without accounting for the extended linear cache size. Retrieve the cache size from HMAT and append that to the cxl region size for the cxl region range that matches the SRAT range that has extended linear cache enabled. The SRAT defines the whole memory range that includes the extended linear cache and the CXL memory region. The new HMAT ECN/ECR to the Memory Side Cache Information Structure defines the size of the extended linear cache size and matches to the SRAT Memory Affinity Structure by the memory proxmity domain. Add a helper to match the cxl range to the SRAT memory range in order to retrieve the cache size. There are several places that checks the cxl region range against the decoder range. Use new helper to check between the two ranges and address the new cache size.
