Revert "radeonfb: accelerate imageblit and other improvements"

This reverts commit b1ee26bab14886350ba12a5c10cbc0696ac679bf, along with
the "fixes" for it that all just caused problems:

 - c4c6fa9891f3d1bcaae4f39fb751d5302965b566 "radeonfb: fix problem with
   color expansion & alignment"

 - f3179748a157c21d44d929fd3779421ebfbeaa93 "radeonfb: Disable new color
   expand acceleration unless explicitely enabled"

because even when disabled, it breaks for people. See

	http://bugzilla.kernel.org/show_bug.cgi?id=12191

for the latest example.
