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
