Kodicom 4400R and Geovision GV-800 code in bttv driver abuses mbox_we (int)
in struct bttv as char *.
Remove this hack and add a proper sw_status array to struct bttv instead.
This is a a preparation to remove mbox_we.

Just opening the radio tuner should not cause a switch to the radio tuner.
Only after calling g/s_tuner or g/s_frequency should this happen.
This prevents audio being unmuted as soon as the driver is loaded because
some process opens /dev/radioX just to see what sort of node it is, which
switches on the radio tuner and unmutes audio.
This code can be improved further by actually keeping track of who owns the
tuner and returning -EBUSY if switching tuner modes will cause problems.
But for now just fix the annoying case where on boot the radio turns on
automatically.

The 'current_norm' field cannot be used if multiple device nodes (video and
vbi in this case) set the same std.

Note that the private chroma agc control has been replaced with the standard
CHROMA_AGC control.
Also fixes a mute/automute problem where closing the file handle would force
mute on. That's not what you want since that would make the mute state out of
sync with the mute control. Instead check against the user count.

Set an initial frequencies when the driver is loaded. That way G_FREQUENCY will
give a frequency that corresponds with reality.

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.
