2011-05-20[media] zoran: Drop unused module parameters encoder and decoderJean Delvare
The ability to force the encoder or decoder chip was broken by commit 0ab6e1c38d80ab586e3a1ca9e71844131d9f51dc in February 2009. As nobody complained for over 2 years, I take it that these parameters were no longer used so we can simply drop them.

Thanks to some excellent investigative work by Douglas Clowes, it was uncovered that the older w83667hg Nuvoton chip functions with this driver after actually enabling the CIR function via its multi-function chip config register. The CIR and CIR wide-band sensor enable bits are just in a different place on this hardware, so we only poke register 0x27 on 677 hardware now, and we poke register 0x2c on the 667 now.

Also, expand the list of known hardware to include both an earlier and a later generation chip that this driver should function with. Douglas has an older w83667hg variant, that with a touch more work, will be supported by this driver, and Lutz has a newer w83677hg variant that works without any further modifications to the driver.
