drm/bochs: Implement struct drm_mode_config_funcs.mode_valid
The implementation of struct drm_mode_config_funcs.mode_valid verifies
that enough video memory is available for a given display mode. This
replaces similar functionality in bochs_connector_mode_valid().
v2:
* remove bochs_connector_mode_valid(), which now serves no purpose
