Now that the SPDX tag is in all comedi files, that identifies the
license in a specific and legally-defined manner. So the extra GPL text
wording can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/staging/comedi files files with the correct SPDX
license identifier based on the license text in the file itself. The
SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

Fix checkpatch.pl warnings of the form "function definition argument
'foo' should also have an identifier name".

The Comedi "comedi_isadma.h" header is included by the source for the
"comedi_isadma" helper module and other modules that use it. It does
not compile cleanly when it is the first header file included. It uses
the `dma_addr_t` type, so include <linux/types.h> to declare it. (Also,
that indirectly takes care of the use of `NULL`.) It uses `struct
comedi_device *` in various function prototypes, so add an incomplete
declaration of `struct comedi_device`.

Introduce a new helper module to consolidate all the ISA DMA code. This will
allow removing the "depends on ISA_DMA_API" from the legacy drivers that can
use DMA for async command support.
This module is complete based on the various uses of ISA DMA in the comedi
drivers.
