Enable generic 8255 support.

You should enable compilation this driver if you plan to use a board
that has an 8255 chip. For multifunction boards, the main driver will
configure the 8255 subdevice automatically.

Note that most PCI 8255 boards do NOT work with this driver, and
need a separate driver as a wrapper.

To compile this driver as a module, choose M here: the module will be
called 8255.
