Douglas Anderson 63358e24ee drm/panel: panel-simple: Cache the EDID as long as we retain power 
It doesn't make sense to go out to the bus and read the EDID over and
over again. Let's cache it and throw away the cache when we turn power
off from the panel. Autosuspend means that even if there are several
calls to read the EDID before we officially turn the power on then we
should get good use out of this cache.
