[6/7] drm/drivers: drop redundant drm_edid_to_eld() calls

drm_add_edid_modes() now fills in the ELD automatically, so the calls to
drm_edid_to_eld() are redundant. Remove them.

All the other places are obvious, but nv50 has detached
drm_edid_to_eld() from the drm_add_edid_modes() call.

This being the only call outside a .get_modes() hook means this is the
only one that might change some behaviour.

Looks like nv_connector->edid gets updated in .detect() as one might
expect, so in theory we might get a mismatch between the
drm_detect_monitor_audio(edid) check above and the actual eld contents
here if .detect() gets called without .get_modes(). Not a problem for
the probe helper's .fill_modes(), but eg. the poll helper does do that.

I guess we could always consider doing the edid_to_eld() already from
.detect()/.force() for all drivers if we think there would be a good
reason to populate the ELD even if .get_modes()/.fill_modes() hasn't
been called.
