Subject: [PATCH] drm/gma500/psb_intel_modes: Remove unused psb_intel_ddc_probe

From: "Dr. David Alan Gilbert" <linux@...blig.org>

psb_intel_ddc_probe() was added in 2011 by
commit 89c78134cc54 ("gma500: Add Poulsbo support")
but has remained unused (probably because drm_get_edid is used
instead).

Remove it.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
