We want to move drm_panel.o from the main drm module to a new drm_panel module, but there is one function in the drm module that calls into drm_panel.c code: drm_of_find_panel_or_bridge() (drm_of.c, drm module) -> calls of_drm_find_panel (drm_panel.c, future drm_panel module) Avoid this issue by moving drm_of_find_panel_or_bridge() to drm_panel.c. Update Kconfig symbols of drivers calling drm_of_find_panel_or_bridge() to select DRM_PANEL when this is not done already. No functional changes, just moving code around.
