drm/bridge: it6505: Add pre_enable/post_disable callback

Browse source

Add atomic_pre_enable and atomic_post_disable callback to make sure the
bridge is not powered off until atomic_post_disable is called. This
prevents a power leakage when it6505 is powered off, but the upstream
DRM bridge is still sending display signals.
