[PATCH] drm: make DRM_DEBUG_MODESET_LOCK depend on DRM

[Lukas Bulwahn]

If DEBUG_KERNEL is selected with a kernel build without DRM, Kconfig still
asks if DRM_DEBUG_MODESET_LOCK is to be selected or not, although this has
no influence on the kernel without DRM.

Make DRM_DEBUG_MODESET_LOCK depend on DRM to avoid needless questions
during kernel build configuration.
