efi_loader: fix efi_add_known_memory()

Browse source 
In efi_add_known_memory() we currently call board_get_usable_ram_top() with
an incorrect value 0 of parameter total_size. This leads to an incorrect
value for ram_top depending on the code in board_get_usable_ram_top().

Use the value of gd->ram_top instead which is set before relocation by
calling board_get_usable_ram_top().

Fixes: 7b78d6438a ("efi_loader: Reserve unaccessible memory")
