Subject: atyfb: Remove unneeded calls to wait_for_idle
From: "Antonino A. Daplas" <adaplas@xxxxxxxxx>
The drawing functions of atyfb is unecessary syncing the GPU which is
affecting performance. Remove the calls, any direct access by fbcon to the
framebuffer will always be preceeded by a call to atyfb_sync().
