drm/bridge: lt9611: use HDMI Connector helper to set InfoFrames

Use new HDMI Connector helpers in the Lontium LT9611 bridge driver.
Program InfoFrames using the helper's callbacks. Also use TMDS char rate
validation callback to filter out modes, instead of hardcoding 4k@30.

The Audio InfoFrame isn't yet handled by these helpers, it requires
additional drm_bridge interface changes.
