The app does not have this symbol. Also the memory where the app is
loaded is not under U-Boot's control.
There is no sense in relocating from one alloced region to another.
U-Boot is not able to relocate to the top of memory, nor decide what
other parts of memory are used for.
For these reasons, the EFI app skips relocation. It is not running at
the address pointed to by the _start symbol.
So disable this reservation for the EFI app.
