radeonfb: Disable new color expand acceleration unless explicitely enabled

This new color expansion acceleration for radeonfb appears to trigger
problems with X on VT switch and suspend/resume on some machines. It
might be a problem in the VT layer or in X, but I haven't quite found
it yet, so in the meantime, this disables the acceleration by default,
reverting to 2.6.27 state. It can be enabled using the "accel_cexp"
module parameter or fbdev argument.
