msm: mdss: update the clocks for slave controller

Browse source 
While updating refresh rate through dynamic fps node,
clock calculations are still needed for the slave controller
and enablement of clock for slave controller is not needed.
This change fixes clock updation of slave controller with
dynamic fps feature enabled.
