+ Report status code listener for PEI. This is used to record the performance
+ data for S3 FullResume in FPDT.
+
+ @param[in] PeiServices An indirect pointer to the EFI_PEI_SERVICES table published by the PEI Foundation.
+ @param[in] CodeType Indicates the type of status code being reported.
+ @param[in] Value Describes the current status of a hardware or software entity.
+ This included information about the class and subclass that is used to
+ classify the entity as well as an operation.
+ @param[in] Instance The enumeration of a hardware or software entity within
+ the system. Valid instance numbers start with 1.
+ @param[in] CallerId This optional parameter may be used to identify the caller.
+ This parameter allows the status code driver to apply different rules to
+ different callers.
+ @param[in] Data This optional parameter may be used to pass additional data.
+
+ @retval EFI_SUCCESS Status code is what we expected.
+ @retval EFI_UNSUPPORTED Status code not supported.
