drm/msm/sde: turn on mdp clock before rsc mode_2 exit 



Input touch event handler was turning on sde_rsc
clocks followed by mdss core gdsc without turning on
mdp clock. This sequence may cause the link clock
on failure. Input touch event must also follow the
pre_kickoff sequence due to mmcx dependency.
