video: fix semantics of of_display_timings_exist()

The function currently uses of_parse_phandle() to evaluate a
'display-timings' property (pointing to a node that contains the
actual timings) rather than a node named 'display-timings' containing
the timings, which is how the DTB layout actually is.

Use of_get_child_by_name() to find a node by this name instead.
