While investigating the users of (now static) fb_display, I noticed
the DECstation

search_tc_card() was removed in in 2007 in commit
b454cc6636d254fbf6049b73e9560aee76fb04a3 ("[TC] MIPS: TURBOchannel
update to the driver model").

include/video/fbcon.h was moved to drivers/video/console/fbcon.h in ... 2002.

Anyone who cares to resurrect it? If not, we should just remove it.
