[U-Boot] [PATCH 1/3] efi_loader: fix GetMemoryMap()

[Heinrich Schuchardt]

The sandbox uses two different address rooms - one used internally by the
sandbox and one usable for EFI.

Very unfortunately this has spilled into the EFI coding.

In efi_get_memory_map() we have to map the returned physical start
addresses to EFI usable addresses.
