comedi: comedi_8255: Conditionally remove I/O port support
In a future patch, the port I/O functions (`inb()`, `outb()`, and
friends will only be declared in the `HAS_IOPORT` configuration option
is enabled.
The comedi_8255 module supports both port I/O and memory-mapped I/O.
Conditionally compile the parts of the module that use port I/O if and
only if the `CONFIG_HAS_IOPORT` macro is defined so that it can still be
built if the port I/O functions have not been declared. If the
`CONFIG_HAS_IOPORT` macro is undefined, replace the GPL-exported
`subdev_8255_io_init()` function with a dummy static inline version that
just returns `-ENXIO`.

comedi: comedi_8255: Rework subdevice initialization functions
Comedi drivers can initialize an 8255 subdevice in I/O space by calling
`subdev_8255_init()`, or in memory-mapped I/O space by calling
comedi: comedi_8255: Rework subdevice initialization functions
Comedi drivers can initialize an 8255 subdevice in I/O space by calling
`subdev_8255_init()`, or in memory-mapped I/O space by calling
`subdev_8255_mm_init()`, or by supplying a call-back function pointer
and context to either of those functions. Change it so that a new
function `subdev_8255_cb_init()` shall be called instead when supplying
a callback function and context, and remove the call-back function
parameter from `subdev_8255_init()` and `subdev_8255_mm_init()`.
Also rename `subdev_8255_init()` to `subdev_8255_io_init()`. The
parameters are changing, so might as well rename it at the same time.
Also rename the `regbase` member of `struct subdev_8255_private` to
`context` since this holds the context for the call-back function call.

comedi: Move and rename "8255.h" to <linux/comedi/comedi_8255.h>

comedi: Move and rename "8255.h" to <linux/comedi/comedi_8255.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 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.
