The pac7302 and pac7311 driver still contains some comments from before
they were separated, such as marking certain functions 7302 or 7311 only,
with the new split drivers these make no sense, remove them.
Also removed the empty/unused sd_stop0 function from pac7311.c

Allow users of gspca/autogain_functions.h to declare which of the autogain
algoritms they are going to use. This allows us to remove the hacks from
drivers which don't use coarse_grained_expo_autogain.

This converts the drivers in drivers/media/* to use the

simpler.
Added bonus is that it removes some unneeded kernel log messages about
drivers loading and/or unloading.

The errors were found by checkpatch.pl. Most fixes are:
- remove spaces followed by TAB(s),
- split lines greater than 80 characters,
- move most '{'s from start of line to end of previous line.
(Some '{'s at start of line remain when the '}'s are on the same line)

This patch fixes possible race conditions in queue management with SMP:
when a frame was completed, the irq function tried to use the next frame
buffer. At this time, it was possible that the application on an other
processor updated the frame pointer, making the image to point to a bad
buffer.
The patch contains two main changes:
- the image transfer uses the queue indexes which are protected against
simultaneous memory access,
- the image pointer which is used for image concatenation is only set at
interrupt level.
Some subdrivers which used the image pointer have been updated.

My experience with fixing up the controls for the PAS sensors in
sonixb, has lead me to re-investigate the exposure control for the
pac7302. I've now found a regular exposure register in register bank 3
(which seems to be the sensor registers bank), and with this added a proper
fine grained exposure control. This patch also updates the do_autogain
function to work properly with this new finer grained control.

All PAC7311 specific functions remain in pac7311.c. All PAC7302 specific
functions are moved to pac7302.c. The USB device table is also divided into
two parts. This makes it possible to remove the sensor specific decisions
from different functions and also remove sensor infromation from the USB
device table.
The common functions are just copied to both subdrivers. These common
functions can be separated later to a common file or helper module.
