[U-Boot] [PATCH v5 03/13] efi: sandbox: Adjust memory usage for sandbox

[Simon Glass]

With sandbox the U-Boot code is not mapped into the sandbox memory range
so does not need to be excluded when allocating EFI memory. Update the EFI
memory init code to take account of that.

Also use mapmem instead of a cast to convert a memory address to a
pointer.
