It conflicts with tidss's writeback code in TI kernel, when compiling tidss and omapfb into the 
kernel. I thought this is the easiest way to resolve that, as all the removed code is dead code, 
instead of trying to invent new names in tidss for a lot of functions.

Probably the functions in tidss still could use some renaming in the future, but I didn't want to be 
forced to do that because of omapfb's dead code...

So, not a super good reason, but on the other hand, removing dead code is always a good thing.
