[PATCH/RFC] deprecate some drivers

[Jeff Garzik]

I'm looking to eliminate some horribly broken/dup drivers.  Since 2.6 is 
an ongoing matter, I want a 'flashing-red warning sign' that drivers 
will soon be disappearing, rather than just killing the driver and 
listening for the screams.

IPhase driver is broken+abandoned, and xirtulip is 
broken+duplicate+abandoned, and are two prime candidates for my prefence 
of handling this matter:  CONFIG_DEPRECATED.

See patch for example.
