[PATCH] efi: payload: be explicit about incompatibility with CONFIG_HAVE_OPTEE

[Ahmad Fatoum]

barebox PBL expects OP-TEE at the end of the initial memory, which
doesn't make sense for barebox as EFI app as the initial memory is just
16M of freshly allocated EFI memory.

Booting barebox via the EFI stub while OPTEE support is enabled will
thus normally hang. Until the PBL OPTEE code is adapted, refuse this
bogus configuration.
