MdePkg: Use VENDOR_DEVICE_PATH structure for Debug Port device path
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; Cc: Ruiyu Ni <ruiyu.ni@intel.com> Cc: Michael D Kinney <michael.d.kinney@intel.com> Cc: Liming Gao <liming.gao@intel.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Dandan Bi <dandan.bi@intel.com> Reviewed-by: Ruiyu Ni <ruiyu.ni@intel.com>
