cx23885: Adding analog video/audio support for the HVR-1250 Rev E2

From: Steven Toth

Includes a workaround for field ordering out of the DIF (where NTSC is
arriving bottom field first). Various timing changes in the 25840
related to clocking and general DIF related registers for tuner vs
non-tuner inputs.

cx23885: Stop the risc video fifo before reconfiguring it.

cx23885: Stop the risc video fifo before reconfiguring it.

From: Steven Toth

Safety reasons. We shouldn't be trying to reconfigure a risc
processor instruction queue unless it's stopped.

cx23885: Avoid incorrect error handling and reporting

cx23885: Avoid incorrect error handling and reporting

From: Steven Toth

Previous driver over-reported errors and stopped the video fifo
(causing video to stop) if 1) A risc error occured 2) The risc processor
detected that it has missing lines in the video frame 3) The risc fifo
is about to overflow.

The previous driver reported all three of these cases as risc errors
when this is technically not correct. So, the function was cleaned up.

1. Ensure that risc opcode related errors are correctly shown as such,
and not overly reported for non-risc-opcode cases.
2. Ensure that line sync and overflow errors are not reported as opcode errors.
3. Ensure that only the risc-op-code case can stop the fifo and dump channel
/ risc processor information.

The net result is that if video becomes unstable, cable disconnect, this will
not trigger a stop of the video firmware (due to missing lines errors).

cx23885: Avoid stopping the risc engine during buffer timeout.

cx23885: Avoid stopping the risc engine during buffer timeout.

From: Steven Toth

1. Removed the verbose 'dump channel state to console', very noisy in
weak signal conditions.
2. No need for the video buffer timeout to stop the risc engine here.
Clearer and easier to maintain if start_video_dma() is the single
place that this is done.

cx23885: hook the audio selection functions into the main driver

From: Steven Toth

Ensure audio is established at driver start.
Ensure the correct defaults are established for the audio path if
the cards struct has nothing defined.
Allow the caller to select one of the two baseband input paths.
