Always call Radeon_InitCP ; it explicitly checks if acc_dma is set and skips 

parts of the init sequence if that's not the case anyways. This correctly
initializes the engine lock and a few other things, fixing the deadlock in
ticket #2893. This also seems to result in somewhat improved graphics
performance, at least on my X800.
