auxdisplay: panel: Remove unused callback binding code

Browse Source 
panel_bind_callback() has been compiled out with #if 0 since
the commit 630231776d ("Staging: panel: remove support
for smartcards") in v2.6.29 and now has no callers. Remove
the dead function to reduce maintenance burden.

No functional change.
