/**
Publishes an interface that allows PEIMs to report status codes.
This function implements EFI_PEI_PROGRESS_CODE_PPI.ReportStatusCode().
It publishes an interface that allows PEIMs to report status codes.
@param PeiServices An indirect pointer to the EFI_PEI_SERVICES table published by the PEI Foundation.
@param CodeType Indicates the type of status code being reported.
@param Value Describes the current status of a hardware or
software entity. This includes information about the class and
subclass that is used to classify the entity as well as an operation.
For progress codes, the operation is the current activity.
For error codes, it is the exception.For debug codes,it is not defined at this time.
@param Instance The enumeration of a hardware or software entity within
the system. A system may contain multiple entities that match a class/subclass
pairing. The instance differentiates between them. An instance of 0 indicates
that instance information is unavailable, not meaningful, or not relevant.
Valid instance numbers start with 1.
@param 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 Data This optional parameter may be used to pass additional data.
@retval EFI_SUCCESS The function completed successfully.
