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

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.
