Provides an interface that a software module can call to report an ASF PEI status code.
The extension to report status code to Intel AMT, so that Intel AMT PET message will
be sent out in PEI.
@param[in] PeiServices General purpose services available to every PEIM.
@param[in] This This interface.
@param[in] Type 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 The function completed successfully
@retval EFI_DEVICE_ERROR The function should not be completed due to a device error.
