DynamicTablesPkg: SSDT Serial Port generator
    
    Most platforms have several serial ports. These serial ports
    are described to an operating system using definition block
    tables.
    
    The SSDT Serial Port Table Generator uses the Configuration
    Manager protocol to obtain information for the Serial Ports
    on the platform. The serial ports are described using the
    CM_ARM_SERIAL_PORT_INFO structure. The EArmObjSerialPortInfo
    ID is used to represent a standard serial port.
    
    The SSDT Serial port fixup library provides interfaces to
    generate a SSDT Serial port table based on the serial port
    information. The SSDT Serial Port Table Generator uses the
    SSDT serial port fixup library to build serial port
    definition blocks and installs the SSDT tables.
