Fix two smatch warnings:
drivers/staging/media/atomisp//pci/ia_css_firmware.h:52:29: warning: 'struct device' declared inside parameter list will not be visible outside of this definition or declaration
drivers/staging/media/atomisp//pci/ia_css_control.h:49:24: warning: 'struct device' declared inside parameter list will not be visible outside of this definition or declaration
Add '#include <linux/device.h>' to ia_css_firmware.h so struct device is defined.
ia_css_control.h includes ia_css_firmware.h, so it is sufficient to
just modify ia_css_firmware.h.

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.

The atomisp driver has its own error codes under the
ia_css_err.h file. On several places, those got already
replaced by standard error codes, but there are still a
lot more to be fixed.
Let's get rid of all of those, mapping them into
the already-existing set of Linux error codes.

The printed message when a firmware version is wrong says nothing
usefull:
atomisp-isp2 0000:00:03.0: Fw version check failed.
atomisp-isp2: probe of 0000:00:03.0 failed with error -22
Print the expected and the received firmware version instead.
In order to do that, the firmware functions will need at least
a struct device pointer, so pass it.
While writing this patch, it was noticed that some of the
abstraction layers of this driver have functions that are never
called, but use this interface. Get rid of them.

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.
