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.
