spark: make cVideo::Standby more robust

Browse Source 
There are a few glitches in the framebuffer driver we need to work
around. For now, let's:
 * close and reopen the video device when going in / out of standby
 * only enable HDMI when coming out of standby
Additionally, don't call Standby() when shutting down neutrino.
