Subject: [PATCH] efi: EFI_DISABLE_RUNTIME should depend on EFI

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 with EFI support.

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