drm/omap: dss: Modify omapdss_find_output_from_display() to return channel
The omapdss_find_output_from_display() function is only used to retrieve
the dispc channel corresponding to the display. Return the dispc channel
directly, and rename the function to omapdss_device_get_dispc_channel()
to match its new purpose.
The dssdev->id check is removed as the dssdev is guaranteed to be an
output and have a non-zero id, as proved by the lack of crash despite
the caller never checking the returned pointer before dereferencing it.
As the function is not specific to outputs anymore, move it from
output.c to base.c.
