Subject: [PATCH 7/7] drm: do not change selected options based on EXPERT mode

EXPERT mode is designed to toggle visibility of config options. It should
not have any other effect on config values. Imagine if a user wants to
tweak a single value that is protected by EXPERT mode. If they enable
EXPERT mode to change that single option, they might get side effects from
other subsystems which they didn't expect. This makes EXPERT mode totally
useless. Hence, simply let the user always select the framebuffer-console
manually.
Furthermore, with kmscon or wayland, users might want to disable CONFIG_VT
which is currently automatically selected by DRM_KMS_HELPER through
FRAMEBUFFER_CONSOLE if !EXPERT.
