media: meye: remove this deprecated driver

The meye driver does not use the vb2 framework for streaming
video, instead it implements this in the driver. This is error prone,
and nobody stepped in to convert this driver to that framework.

The hardware is very old, so the decision was made to remove it
altogether.

-
-This driver enable the use of video4linux compatible applications with the
-Motion Eye camera. This driver requires the "Sony Laptop Extras" driver (which
-can be found in the "Misc devices" section of the kernel configuration utility)
-to be compiled and installed (using its "camera=1" parameter).
-
-It can do at maximum 30 fps @ 320x240 or 15 fps @ 640x480.
-
-Grabbing is supported in packed YUV colorspace only.
-
-MJPEG hardware grabbing is supported via a private API (see below).
-
-Hardware supported
-------------------
-
-This driver supports the 'second' version of the MotionEye camera :)
-
-The first version was connected directly on the video bus of the Neomagic
-video card and is unsupported.
-
-The second one, made by Kawasaki Steel is fully supported by this
-driver (PCI vendor/device is 0x136b/0xff01)
-
-The third one, present in recent (more or less last year) Picturebooks
-(C1M* models), is not supported. The manufacturer has given the specs
-to the developers under a NDA (which allows the development of a GPL
-driver however), but things are not moving very fast (see
-http://r-engine.sourceforge.net/) (PCI vendor/device is 0x10cf/0x2011).
-
-There is a forth model connected on the USB bus in TR1* Vaio laptops.
-This camera is not supported at all by the current driver, in fact
-little information if any is available for this camera
-(USB vendor/device is 0x054c/0x0107).
-
-Driver options
---------------
-
-Several options can be passed to the meye driver using the standard
-module argument syntax (<param>=<value> when passing the option to the
-module or meye.<param>=<value> on the kernel boot line when meye is
-statically linked into the kernel). Those options are:
-
-.. code-block:: none
-
-	gbuffers:	number of capture buffers, default is 2 (32 max)
-
-	gbufsize:	size of each capture buffer, default is 614400
-
-	video_nr:	video device to register (0 = /dev/video0, etc)
-
-Module use
-----------
-
-In order to automatically load the meye module on use, you can put those lines
-in your /etc/modprobe.d/meye.conf file:
-
-.. code-block:: none
-
-	alias char-major-81 videodev
-	alias char-major-81-0 meye
-	options meye gbuffers=32
-
-Usage:
-------
-
-.. code-block:: none
-
-	xawtv >= 3.49 (<http://bytesex.org/xawtv/>)
-		for display and uncompressed video capture:
-
-			xawtv -c /dev/video0 -geometry 640x480
-				or
-			xawtv -c /dev/video0 -geometry 320x240
-
-	motioneye (<http://popies.net/meye/>)
-		for getting ppm or jpg snapshots, mjpeg video
-
-Bugs / Todo
------------
-
-- 'motioneye' still uses the meye private v4l1 API extensions.

-Private API
------------
-
-The driver supports frame grabbing with the video4linux API,
-so all video4linux tools (like xawtv) should work with this driver.
-
-Besides the video4linux interface, the driver has a private interface
-for accessing the Motion Eye extended parameters (camera sharpness,
-agc, video framerate), the snapshot and the MJPEG capture facilities.
-
-This interface consists of several ioctls (prototypes and structures
-can be found in include/linux/meye.h):
-
-MEYEIOC_G_PARAMS and MEYEIOC_S_PARAMS
-	Get and set the extended parameters of the motion eye camera.
-	The user should always query the current parameters with
-	MEYEIOC_G_PARAMS, change what he likes and then issue the
-	MEYEIOC_S_PARAMS call (checking for -EINVAL). The extended
-	parameters are described by the meye_params structure.
-
-
-MEYEIOC_QBUF_CAPT
-	Queue a buffer for capture (the buffers must have been
-	obtained with a VIDIOCGMBUF call and mmap'ed by the
-	application). The argument to MEYEIOC_QBUF_CAPT is the
-	buffer number to queue (or -1 to end capture). The first
-	call to MEYEIOC_QBUF_CAPT starts the streaming capture.
-
-MEYEIOC_SYNC
-	Takes as an argument the buffer number you want to sync.
-	This ioctl blocks until the buffer is filled and ready
-	for the application to use. It returns the buffer size.
-
-MEYEIOC_STILLCAPT and MEYEIOC_STILLJCAPT
-	Takes a snapshot in an uncompressed or compressed jpeg format.
-	This ioctl blocks until the snapshot is done and returns (for
-	jpeg snapshot) the size of the image. The image data is
-	available from the first mmap'ed buffer.
-
-Look at the 'motioneye' application code for an actual example.
