comedi: Move "comedi_8254.h" to <linux/comedi/comedi_8254.h>
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 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/".
