When a device path protocol is installed write the device
path to the console in debug mode.
For printing the new macro EFI_PRINT is used, which can be reused
for future diagnostic output.
Remove unused EFI_PRINT_GUID macro

v3
Avoid memory leak. Use printf("%pD") for device path output.
v2
Remove unused EFI_PRINT_GUID macro.
Use new macro EFI_PRINT to output device path.
