The visl driver supports both frame and slice mode, with and without a
start-code. But, the range and default for these enum controls was not
set, which currently limits the decoder to enums with a value of 0. Fix
this by setting the decoder mode and start code controls for both the
H.264 and HEVC codecs.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/media to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

The text written on the output frames stable for a given input.
Remove the unstable elements like pointers, buffer indexes or queues
status so that frames are always identical and can be compared against
a reference in automatic tests.
As the unstable information can be relevant when debugging the API, add
a tpg_verbose parameter to show them.

This avoids confusion with default values and lets userspace
programs get the modules parameters values at run time.
This can be useful when setting up a test suite.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

A virtual stateless device for stateless uAPI development purposes.
This tool's objective is to help the development and testing of
userspace applications that use the V4L2 stateless API to decode media.
A userspace implementation can use visl to run a decoding loop even when
no hardware is available or when the kernel uAPI for the codec has not
been upstreamed yet. This can reveal bugs at an early stage.
This driver can also trace the contents of the V4L2 controls submitted
to it. It can also dump the contents of the vb2 buffers through a
debugfs interface. This is in many ways similar to the tracing
infrastructure available for other popular encode/decode APIs out there
and can help develop a userspace application by using another (working)
one as a reference.
Note that no actual decoding of video frames is performed by visl. The
V4L2 test pattern generator is used to write various debug information
to the capture buffers instead.
