This ioctl is defined as IOW, so pass the argument by value instead of by
reference. I could have chosen to add const instead, but this is 1) easier
to handle in drivers and 2) consistent with the s_std subdev operation.

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

The code attempts to maintain a "user format" and a "sensor format",

For the ov7670 camera to return images at the requested frame rate,
it needs to make calculations based on the clock speed, which is
a completely external factor (depends on the wiring of the system).

On the XO-1.5, which is the only known via-camera user, the camera
is clocked at 90MHz.

Pass this information to the ov7670 driver, to fix an issue where
a framerate of 3x the requested amount was being provided.

The RGB mode does not work correctly. It captures fine at 640x480
but whenever the scaling engine is used to produce another resolution,
color corruption occurs (lots of erroneous pink and green).

It is not clear how the scaling engine is supposed to work and how
it knows which pixel format it is dealing with. Work around this
problem by disabling RGB support. YUYV scaling works just fine.

Test case:

	gst-launch v4l2src ! video/x-raw-rgb,bpp=16,width=320,height=240 ! \
	ffmpegcolorspace ! xvimagesink

The code that checks the OLPC serial port is never built at the moment,
because CONFIG_OLPC_XO_1_5 doesn't exist and probably won't be added.

Fix it so that it gets compiled in, only executes on OLPC laptops, and
move the check into the probe routine.

The compiler is smart enough to eliminate this code when CONFIG_OLPC=n
(due to machine_is_olpc() always returning false).
