Added V4L2_CID_COLOR_KILLER control to the bt8xx driver.
The control V4L2_CID_PRIVATE_CHROMA_AGC was changed too because
with this change the bttv driver must touch two bits in the
SC Loop Control Registers, for controls V4L2_CID_COLOR_KILLER
and V4L2_CID_PRIVATE_CHROMA_AGC.

drivers/media/tuners/mt2063.c:2286:14: warning: no previous prototype for 'tuner_MT2063_ClearPowerMaskBits' [-Wmissing-prototypes]

Several of those warnings are real bugs: the error status code
used to be unsigned, but they're assigned to negative error
codes.

Fix it by using unsigned int.

While here, comment the two power management functions, while we
don't add a code there to properly handle tuner suspend/resume.

"carrier" comes from a get_user() in ir_lirc_ioctl().  We need to test
that it's not zero before using it as a divisor.  It might have been
nice to test for this ir_lirc_ioctl() but the mceusb driver uses zero to
disable carrier modulation.
The bug in redrat3 is a little more subtle.  The ->carrier is passed to
mod_freq_to_val() which uses it as a divisor.
