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 system_types.h

This is just a wrapper for system_local.h.

media: atomisp: change the type returned by mmgr alloc

The mmgr alloc code returns a different type than hmm, due to
some abstraction layer.

Change the driver to use just one type to represent the
hmm memory.

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.
