msm: camera: cpp: Vote AHB with clock enabled and no mem retention

Vote for AHB bandwidth after clocks are enabled. For bandwidth
voting clocks need to be on. Set the memory retention flags for
certain hardware clocks to save power, memory does not need to
be retained for these clocks since the driver reinitializes the
jpeg hardware whenever the clocks are turned on.
