[U-Boot] [PATCH v3 1/9] efi_loader: eliminate sandbox addresses

[Heinrich Schuchardt]

Do not use the sandbox's virtual address space for the internal structures
of the memory map. This way we can eliminate a whole lot of unnecessary
conversions.

The only conversion remaining is the one when adding known memory.
