lgdt330x: add additional FEC control configuration option
From: Michael Krufky <mkrufky@linuxtv.org>
Allow the following configuration, by passing clock_polarity_flip = 2:
Enable FEC automatic reset. Disable spectrum inversion.
Enable viterbi resynchronization. Set polarity indicator high.
Enable error flag insertion.
Thanks to Daniel Gimpelevich, for discovering that this configuration
is used on the AVerMedia AVerTVHD Volar.
