While working on the generic mode_valid() implementation for the HDMI
Connector framework I noticed that unlike other DRM objects
drm_connector accepts non-const pointer to struct drm_display_mode,
while obviously mode_valid() isn't expected to modify the argument.

Mass-change the DRM framework code to pass const argument to that
callback.

Note: yes, I understand that this change might be hard to review and
merge. The only viable option that I foresee is to add new callback,
having the const argument and migrate drivers into using it one by one.
