Scatter/Gather needs. The original approach can't even work for those

By default, we allocate DMA buffers when actually reading from the video
capture device. On a system with 128MB or 256MB of ram, it's very easy
for that memory to quickly become fragmented. We've had users report
having 30+MB of memory free, but the cafe_ccic driver is still unable to
allocate DMA buffers.
Our workaround has been to make use of the 'alloc_bufs_at_load' parameter
to allocate DMA buffers during device probing. This patch makes DMA
buffer allocation happen during device probe by default, and changes
the parameter to 'alloc_bufs_at_read'. The camera hardware is there,
if the cafe_ccic driver is enabled/loaded it should do its best to ensure
that the camera is actually usable; delaying DMA buffer allocation
saves an insignicant amount of memory, and causes the driver to be much
less useful.

The v4l tveeprom logic tells us what video standards are supported by
the hardware, however it doesn't directly tell us what should be the
preferred initial standard. For example "NTSC/NTSC-J" devices are
reported by tveeprom as support NTSC-M and PAL-M, and while that might
be true, in the vast majority of cases NTSC-M is really what the user
is going to want. However the driver previously just arbitrarily
picked the "lowest numbered" standard as the initial default, which in
that case would have been PAL-M. (And making matters more confusing -
this only caused real problems on 24xxx devices because the saa7115 on
29xxx seems to autodetect the right answer anyway.) This change
implements an algorithm that uses the set of "supported" standards as
a hint to decide on the initial standard. This algorithm ONLY comes
into play if the driver isn't specifically told what to do; said
another way - the user can always still change the standard via the
sysfs interface, via the usual V4L methods, or even specified as a
module parameter. The idea here is only to pick a better starting
point if the user (or app) doesn't otherwise do something to set the
standard; otherwise this change has no real impact.

Use the balance control to make the mono volume control stereo.
Note that full range isn't supported. The balance control attenuates one
channel by 0 to -63 dB, and the volume control provides additional attenuation
to both channels by another 0 to -63 dB.
So the channel with the most attenuation has a range of 0 to -126 dB, while
the other channel only has a range of 0 to -63 dB. ALSA volume controls don't
appear to support this concept. I just limited the range to 0 to -63 total.
Once you get to -63 dB, you're already at silence, so additional attenuation
is pretty much pointless anyway.

Ignore 0x6b and 0x6f on cx88 boards. Some FusionHDTV cards
have an ir receiver at 0x6b and an RTC at 0x6f which can
get corrupted if probed.

- fixed missing buttons in keymap.
- make function names & descriptions more generic,
since this same ir receiver and remote is used in
many FusionHDTV products.
- miscellaneous cleanups.

I wanted to document the NMI assert issue inside the code, even though
it's already documented in the patch history. If/when the next cx23887
revision appears, is may need to be enabled on that also.
