The revision is part of the pci_dev struct, so there is no need to read it in.

Stop storing the revision and latency in the chip struct, since they're never
used after being printed out when the driver loads.

linux/pci.h wasn't included.  It was getting picked up something else,
probably cx88.h, but this file uses struct pci_dev so it should include pci.h.

Currently the driver turns on audio interrupts, then sets the audio interrupt
mask to select which interrupts to get.  One could received unwanted
interrupts since the mask is set _after_ interrupts have already been turned
on.  Change the order of the operations, and clear any audio interrupt status
bits that are already set for good measure.

Before changing the SRAM FIFO parameters, make sure the FIFO isn't being used.
This shouldn't happen with just the ALSA driver, as it should never try to
turn on FIFO/RISC/DMA while they are already on.  However, the V4L driver
needs to turn the audio FIFO on for analog audio output to work (undocumented
cx88 bug).  The FIFO parameters are in an inconsistent state while they are
updated, and this results in many FIFO sync error IRQs if the FIFO is in use
while it's in this inconsistent state.

Also create and use a bunch of symbolic constants for audio interrupt mask
bits.

When an irq handled by the cx88 core driver (currently IR and errors) occurs
and the cx88-alsa irq handler is the first called, it will claim to have
handled the irq but it doesn't call cx88_core_irq() to handle it.

The means loading cx88-alsa can disable the IR remote.

It turns out that the cx23415/6 DMA engine cannot do scatter/gather DMA
reliably. Every so often depending on the phase of the moon and your
hardware configuration the cx2341x DMA engine simply chokes on it and
you have to reboot to get it working again.

This change replaced the scatter/gather DMA by single transfers at a time,
where the driver is now responsible for DMA-ing each buffer.

UDMA is still done using scatter/gather DMA, that will be fixed soon.

Many thanks to Mark Bryars <mark.bryars@etvinteractive.com> for discovering
the link between scatter/gather and the DMA timeouts.

When there are no more free buffers, then buffers are stolen from the
predma queue. Buffers should be stolen from the head of that queue (which
is where the most recently added buffers are) and all buffers belonging
to a frame should be stolen. Otherwise 'half-frames' would remain in the
queue, which leads to ugly playback and complete sync failure for YUV
buffers.

The CX2341X_ENC_INITIALIZE_INPUT firmware call requires careful handling,
otherwise the computer can freeze or the top-third of the screen can start

In addition the stop capture handling was improved so that the last pending
DMA transfer is also processed. Otherwise this would be the first data that
arrived when a new capture was started which is not what you want.

FM radio transmission use a preemphasis/deemphasis scheme to reduce
high-frequency noise.  The cx88 audio decoder is supposedly set to no
deemphasis by the current driver.

However, the "no deemphasis" setting doesn't work.  On my chip, cx23883, it
produces the same result as the 75 us time constant.  Maybe the default
settings on the cx23881 are for 50 us?

Since the deemphasis time constant varies by country, allow setting it via a
module parameter.
