drm/omap: dss: Create and use omapdss_device_is_registered()

Browse Source 
The omapdss_component_is_loaded() function test whether a component is
loaded by checking whether it is present in the displays list or the
outputs list. Simplify the implementation by checking for the component
in the global omap_dss_device list.
