`external_ai_queue_in_use()` is supposed to return 1 if the external
channel sequencer is in use by an AI command, else return 0. If the
"read" subdevice (which is the AI subdevice) is not busy then no AI
command is running so the external channel sequencer is not in use, so
the function should return 0. Unfortunately, the function's "read"
subdevice busy test is inverted, so the function always returns 0 when
the "read" subdevice is busy. Worse, if the "read" subdevice is
not busy the subsequent call to `use_internal_queue_6xxx()` results in a
null pointer dereference if a previous AI command used a channel list
with a length greater than 1.

external_ai_queue_in_use()"
This reverts commit f5f3a2c6569e ("staging: comedi: cb_pcidas64: change
params to external_ai_queue_in_use()"). The
`external_ai_queue_in_use()` was being called from `ao_cmd()` with
pointers to the "write" subdevice and AO command, but is supposed to
check whether the external AI queue is currently in use by the "read"
subdevice and AI command. In fact, the return value always indicated
that the external AI queue was not in use in this case (because the AO
command's channel list is sequential), so was fairly useless. (However,
even before the reverted commit, the logic in
`external_ai_queue_in_use()` was wrong. That will be corrected in a
subsequent commit.)

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.

Most of the macros in "plx9080.h" that define register values are
single-bits flags of the form `PLX_<REG>_<FLAG>`, or are constant,
multi-bit values of the form `PLX_<REG>_<FIELD>_<VAL>`, or are
non-constant, function-like macros of the form `PLX_<REG>_<FIELD>(x)`.
Some of the macros for constant, multi-bit values do not currently
fit the pattern, so rename them for consistency.

alloc_and_init_dma_members does not affect the interrupt status and is
only called by auto_attach, which also does not affect the interrupt
status. auto_attach() also contains a call to comedi_alloc_devpriv()
which calls kzalloc with GFP_KERNEL flag. Thus, there seems to be no
danger that dma_alloc_coherent can be called with interrupts turned
off, and GFP_KERNEL can be used.

The hardware range code values and list of valid ranges for the AI
subdevice is incorrect for several supported boards. The hardware range
code values for all boards except PCI-DAS4020/12 is determined by
calling `ai_range_bits_6xxx()` based on the maximum voltage of the range
and whether it is bipolar or unipolar, however it only returns the
correct hardware range code for the PCI-DAS60xx boards. For
PCI-DAS6402/16 (and /12) it returns the wrong code for the unipolar
ranges. For PCI-DAS64/Mx/16 it returns the wrong code for all the
ranges and the comedi range table is incorrect.
Change `ai_range_bits_6xxx()` to use a look-up table pointed to by new
member `ai_range_codes` of `struct pcidas64_board` to map the comedi
range table indices to the hardware range codes. Use a new comedi range
table for the PCI-DAS64/Mx/16 boards (and the commented out variants).
