media: atomisp: add SPDX headers

This driver is licensed under GPL 2.0, as stated inside their
headers.

Add the proper tag there. We should probably latter cleanup
the reduntant licensing text, but this could be done later,
after we get rid of other abstraction layers.

media: atomisp: get rid of an error abstraction layer

There is an abstraction layer there meant to convert to
the Linux standard error codes. As the driver now use
such errors everywhere. we can get rid of this.

media: atomisp: get rid of memory_access.c

Now that we have everything in place, we can get rid of the
memory_access abstraction layer.

Now, everything related to heterogeneous memory management
(hmm) is under hmm.c & related pools.

media: atomisp: get rid of most checks for ISP2401 version

There are lots of places inside this driver checking for
ISP2400/ISP2401 verison. Get rid of most of those, while
keep building for both.

Most of stuff in this patch is trivial to solve.

media: atomisp: cleanup directory hierarchy

This driver has very long directories without a good
reason (IMHO). Let's drop two directories from such hierarchy,
in order to simplify things a little bit and make the dir
output a bit more readable.
