[media] cx25840 / cx23885: Fixing audio/volume regression
Since the conversion to subdev in Oct 2010 the audio controls have
not functioned correctly in the cx23885 driver. Passing values of
0-3f did not translate into meaningfull register writes. I've
converted the cx23885 driver to match the cx25840 volume control
definition and now audio is working reliably again.

[media] cx25840: Enable support for non-tuner LR1/LR2 audio inputs
The change effects cx23885 boards only and preserves support for existing
boards. Essentially, if we're using baseband audio into the cx23885 AV
core then we have to patch registers. The cx23885 driver will call
with either CX25840_AUDIO8 to signify tuner audio or AUDIO7 to
signify baseband audio. If/When we become more comfortable with this change
across a series of products then we may decide to relax the cx23885 only
restriction.

[media] Add support for AUX_PLL on cx2583x chips
This adds support for the AUX_PLL in cx2583x chips which is available in
those although the audio part of the chip is not.
The AUX_PLL is used at least by Terratec in their Grabster AV400 device.

V4L/DVB (13089): cx25840: Separate set_audclk_freq functionality for the different chips
Separate out the set_audclk_freq() function into separate functions for the
four families of cores. These cores all use slightly different sample clock
schemes and may be assuming slightly (+/- 3 Hz) different reference frequencies.
The code resuse was not worth the maintenance and testing headache of have all
chips use the same function peppered with conditional logic.
Added comments on how PLL and SRC parameters values are computed. Fixed a few
bugs related to the shared code having a large number of conditional statements.
Noted inconsistencies with FIXME in the comments.
This is done in preparation for getting the CX2388[578] PLL/clock setting logic
cleaned up for CX23888 analog video and IR (which need the VID PLL set right).

V4L/DVB (5997): cx25840: fix audio mute handling and reporting
Audio muting for the tuner input was implemented by stopping the
audio microcontroller and restarting it on unmute. However, it
appears that this method can actually crash the audio firmware.
It's rare and seems to happen with NTSC only.
It has been reimplemented by setting to volume to 0. In addition, the
reporting of the mute state has been improved as well: it used to be
impossible to detect whether the audio was muted by the user or if it
was muted due to the microcontroller trying to detect the audio
standard. This is now clearly stated.

V4L/DVB (3577): Cleanup audio input handling
Cleanup audio input handling in bttv and tvaudio:
- inputs were specified that were never used
- mute was handled as a special input which led to confusing code
- confusing naming made it difficult to see if the setting was for
i2c or gpio.
The old audiochip.h input names moved to tvaudio.h. Currently this
is used both by tvaudio and msp3400 until the msp3400 implements the
new msp3400-specific inputs.
Detect in bttv the tvaudio and msp3400 i2c clients and use these
client pointers to set the inputs directly instead of broadcasting the
command.
Removed AUDC_SET_INPUT. Now replaced by VIDIOC_S_AUDIO. This will be
replaced again later by the new ROUTING commands.
Removed VIDIOC_G_AUDIO implementations in i2c drivers: this command is
a user level command and not to be used internally. It wasn't called at
all anyway.
