V4L/DVB (11070): au0828: Rework the way the analog video binding occurs

Browse Source 
Rework the way boards are managed so that we can change the board description
based on the Hauppauge eeprom (modeled after cx88-cards.c).

Also, make sure that we don't load the analog stack if there are no analog
inputs defined in the board profile.

Thanks to Michael Krufky <mkrufky@linuxtv.org> for providing information on
the various ways different Hauppauge boards can be configured.
