The EFI_DISABLE_RUNTIME config option controls the use of Extensible
Firmware Interface (EFI) runtime services, which matters only if EFI
support is enabled.

Hence add a dependency on EFI, to prevent asking the user about this
control knob when configuring a kernel without EFI support.

Fixes: a031651ff2144a3d ("efi: Allow to enable EFI runtime services by default on RT")

Can we just move this option into the menu/endmenu scope that already
depends on EFI?

We can, and there are other candidates as well. So I'll drop this
patch, and send out another one that covers some other options too.

Thanks,
Ard.
