REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1229
When converting DebugPort device path from text,
current code use VENDOR_DEFINED_MESSAGING_DEVICE_PATH structure
for Debug port device node.
typedef struct {
EFI_DEVICE_PATH_PROTOCOL Header;
EFI_GUID Guid;
UINT8 VendorDefinedData[1];
} VENDOR_DEFINED_MESSAGING_DEVICE_PATH;
And Debugport Device Path is a vendor-defined messaging
device path with no data, only a GUID. So it's better to
use VENDOR_DEVICE_PATH to create the Debug port device node.
typedef struct {
EFI_DEVICE_PATH_PROTOCOL Header;
EFI_GUID Guid;
} VENDOR_DEVICE_PATH;
