msm: kgsl: Turn off the CP_DEBUG dynamic clock

The CP dynamic clock seems to be glitchy when the CP clocks are turned
back on after a power event. Turn off said dynamic clock control at
init time. The impact of leaving the dynamic clock control off is
negligible since the CP clock is only on when the CP is actually in
use.
