I don't think that changing the omap_dss_device structure is the best way
to go about this. Members like power_on_delay and power_off_delay may not
be required by all types of panels. Same goes for the new "name" member since
its only used by the dummy dpi panels.
I think it would be better to go with the approach taken in panel-taal.c
where a struct "panel_config" exists to take care of extra requirements.
The omap_dss_device struct should contain only those members which would be
needed by the interface driver files like dsi.c, dpi.c etc. The rest should be
taken care of the panel drivers internally.
