mdss: dsi: fix DSI clk rate update during dynamic resolution switch

Browse source 
Current implementation updates the DSI link clock rate during UNBLANK.
By this time link rate is already set with a random value, which
might lead to unexpected behaviour. Update the clock during LINK READY
so that the new  values take effect.
