[media] s5p-mfc: Ensure that clock is disabled before turning power off

Browse source 
Move clock disabling before turning power off.  This will enable later
to add calls to clk_prepare/unprepare in the s5p_mfc_power_off() function
to avoid keeping clocks prepared all the time when driver is bound.
