[PATCH] drm/dp-helper: Deprecate old i2c-over-dp_aux heleprs

[Daniel Vetter]

Only gma500 is still using this, once that's converted we can kill all
this code. If that conversion doesn't happen soonish I think we should
just move this helper code into the gma500 driver itself to avoid
abuse from new drivers.
