Skip setting parent with dummy fixed-clock. Upstream linux might declare an additional clock for the mtk timer and that additional clock might also be a fixed-clock defined in DT. Setting parent of a dummy fixed-clock resulta in error hence mtk timer fails to probe.

Skip setting parent to permit correct probe of the mtk timer.
