/**
Convert status code value and extended data to readable ASCII string, send string to serial I/O device.
@param CodeType Indicates the type of status code being reported.
@param 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 Instance The enumeration of a hardware or software entity within
the system. 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 Status code reported to serial I/O successfully.
@retval EFI_DEVICE_ERROR EFI serial device cannot work after ExitBootService() is called.
@retval EFI_DEVICE_ERROR EFI serial device cannot work with TPL higher than TPL_CALLBACK.
