OMAP: DSS2: Remove clk optimization at dss init
DSS enables core clocks for the duration of initialization to avoid unnecessary context saves and restores. With PM runtime the clocks cannot be handled in this way, outside the dss module drivers. Thus we need to remove the optimization. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com>
