[PATCH] parport: add parallel port support for SGI O2 



Add support for the built-in parallel port on SGI O2 (a.k.a.  IP32).
Define a new configuration option: PARPORT_IP32.  The module is named
parport_ip32.

Hardware support for SPP, EPP and ECP modes along with DMA support when
available are currently implemented.

	  SGI O2 machines. This code is also available as a module (say M),
