[PATCH] atyfb (2.6): Memory type correction

This patch changes the memory type message to match reality. This agrees 
with both my hardware and the Mobility register specs.

I took the values from the RAGE II+ manual. So ATI recycled the WRAM value for
Mobility? Unless they never actually made boards with WRAM.

when I'm talking to journalists I just say "programmer" or something like that.

My Rage Pro manual lists WRAM in CONFIG_STAT2.CFG_MEM_TYPEb. And that's 
the only place where WRAM in mentioned as a valid memory type in my 
manuals. Also the values of CFG_MEM_TYPEb look like the xor of 
CONFIG_STAT0.CFG_MEM_TYPE except that WRAM is CFG_MEM_TYPEb=001 and 
CFG_MEM_TYPE=110 is listed as a reserved value.
