[RFC 6/7] drm/omap: dss: Remove display ordering from dss/display.c

[Peter Ujfalusi]

The previous patch implements the ordering of the dss_devices based on DT
aliases in omap_drm.c, so there is no need to do the ordering in
dss/display.c anymore.

At the same time remove the alias member of the omap_dss_device struct
since it is no longer needed. The only place it was used is in the
omapdss_register_display() function.
