drm/tilcdc: Remove the useless module list support

Browse Source 
The tilcdc driver previously supported a sub-module system where
external display drivers (panels, encoders) could register themselves
through tilcdc_module_init() and be automatically initialized through
a module list. This infrastructure became unused after the component
framework support and panel driver was removed.
