Some of the header files in "drivers/comedi/drivers/" are common enough
to be useful to out-of-tree comedi driver modules. Using them for
out-of-tree module builds is hampered by the headers being outside the
"include/" directory so it is desirable to move them.
There are about a half a dozen or so Comedi device drivers that use the
"comedi_isadma" module to add ISA DMA support. The macros and
declarations to use that module are in the "comedi_isadma.h" header file
in the comedi "drivers" directory. Move it into
"include/linux/comedi/".

There are about a couple of dozen or so Comedi device drivers that use
the "comedi_8254" module to add timers based on the venerable 8254
Programmable Interval Timer chip. The macros and declarations to use
that module are in the "comedi_8254.h" header file in the comedi
"drivers" directory. Move it into "include/linux/comedi/".

There are about a couple of dozen Comedi device drivers that use the
"comedi_8255" module to add digital I/O subdevices based on the
venerable 8255 Programmable Peripheral Interface chip. The macros and
declarations to use that module are in the "8255.h" header file in the
comedi "drivers" directory. Move it into "include/linux/comedi/" and
rename it to "comedi_8255.h" for naming consistency reasons.

Move the main COMEDI driver headers out of "drivers/comedi/" into new
directory "include/linux/comedi/". These are "comedidev.h",
"comedilib.h", "comedi_pci.h", "comedi_pcmcia.h", and "comedi_usb.h".
Additionally, move the user-space API header "comedi.h" into
"include/uapi/linux/" and add "WITH Linux-syscall-note" to its
SPDX-License-Identifier.
Update the "COMEDI DRIVERS" section of the MAINTAINERS file to account
for these changes.
