[PATCH 12/15] drm/msm/hdmi: set infoframes on all pre_enable calls

In consequent modeset calls, the atomic_pre_enable() will be called
several times without calling atomic_post_disable() inbetween. Thus
iframes will not be updated for the next mode. Fix this by setting the
iframe outside of the !power_on check.
