/** SerialPort dispatcher.
This disptacher populates the CM_ARCH_COMMON_SERIAL_PORT_INFO structure for
the following CM_OBJ_ID:
- EArchCommonObjConsolePortInfo
- EArchCommonObjSerialDebugPortInfo
- EArchCommonObjSerialPortInfo
A parser parses a Device Tree to populate a specific CmObj type. None,
one or many CmObj can be created by the parser.
The created CmObj are then handed to the parser's caller through the
HW_INFO_ADD_OBJECT interface.
This can also be a dispatcher. I.e. a function that not parsing a
Device Tree but calling other parsers.
@param [in] FdtParserHandle A handle to the parser instance.
@param [in] FdtBranch When searching for DT node name, restrict
the search to this Device Tree branch.
@retval EFI_SUCCESS The function completed successfully.
@retval EFI_ABORTED An error occurred.
@retval EFI_INVALID_PARAMETER Invalid parameter.
@retval EFI_NOT_FOUND Not found.
@retval EFI_UNSUPPORTED Unsupported.
