The driver is for an IP core found on i.MX7 and i.MX8 SoC, so do not
specify a SoC version number in the driver name.
Remove the references to the i.MX7 SoC in the driver symbols and expand
the driver's header with more information about the IP core the driver
controls.
Also rename the associated bindings documentation.

The vimc driver is used for testing purpose, and some test use cases
involve sharing buffers with a consumer device. Consumers often require
DMA contiguous memory, which vimc doesn't currently support. This leads
in the best case to usage of bounce buffers, which is very slow, and in
the worst case in a complete failure.
Add support for the dma-contig allocator in vimc to support those use
cases properly. The allocator is selected through a new "allocator"
module parameter, which defaults to vmalloc.

Modify the scaler subdevice to accept setting the resolution of the source
pad (previously the source resolution would always be 3 times the sink for
both dimensions). Now any resolution can be set at src (even smaller ones)
and the sink video will be scaled to match it.
Test example: With the vimc module up (using the default vimc topology)
media-ctl -d platform:vimc -V '"Sensor A":0[fmt:SBGGR8_1X8/640x480]'
media-ctl -d platform:vimc -V '"Debayer A":0[fmt:SBGGR8_1X8/640x480]'
media-ctl -d platform:vimc -V '"Scaler":0[fmt:RGB888_1X24/640x480]'
media-ctl -d platform:vimc -V '"Scaler":0[crop:(100,50)/400x150]'
media-ctl -d platform:vimc -V '"Scaler":1[fmt:RGB888_1X24/300x700]'
v4l2-ctl -z platform:vimc -d "RGB/YUV Capture" -v width=300,height=700
v4l2-ctl -z platform:vimc -d "Raw Capture 0" -v pixelformat=BA81
v4l2-ctl --stream-mmap --stream-count=10 -z platform:vimc -d "RGB/YUV Capture" \

The result will be a cropped stream that can be checked with the command

The IP block evolved from its rk3288/rk3399 base and the vendor
designates them with a numerical version. rk3399 for example
is designated V10 probably meaning V1.0.
There doesn't seem to be an actual version register we could read that
information from, so allow the match_data to carry that information
for future differentiation.
Also carry that information in the hw_revision field of the media-
controller API, so that userspace also has access to that.
The added versions are:
- V10: at least rk3288 + rk3399
- V11: seemingly unused as of now, but probably appeared in some soc
- V12: at least rk3326 + px30
- V13: at least rk1808

There are several :c:type: definitions there, in order to
do cross-references with the driver's documentation.
Those are broken when docs are built with Sphinx 3.x, as
it would require :c:struct: instead.
For Sphinx < 3.x, the automarkup.py extension is able to do the
replacement already, and a future improvement on it should make
it also work with Sphinx 3.x.
So, get rid of the usage of the :c:type: macro there.

--------------------------------------------------------------
The driver is deprecated and scheduled for removal by the end
of 2020.
In order to prevent removal the following actions would have to
be taken:
- clean up the code
- convert to the vb2 framework
- fix the disconnect and free-on-last-user handling (i.e., add
a release callback for struct v4l2_device and rework the code
to use that correctly).
