Subject[PATCH 07/10] efi/libstub: drop explicit 64-bit protocol definitions
Date
Mixed mode involves casting 64-bit native calls to 32-bit EFI calls,
which requires explicit 32-bit protocol definitions. Native calls
are always done using the protocol definitions that use native types,
and so the explicit 64-bit ones are redundant. Remove them.
