viafb: make suspend and resume work (on all machines?)
This patch removes the dangerous suspend and resume code that was developed for VX855 only. After this the framebuffer is expected to cause no longer serious (freezing) issues on any machines. However the hardware acceleration is broken now so only doing resume with unaccelerated framebuffers is save. This did not work previously as the 2D engine is not mapped if the framebuffer is not accelerated. The acceleration issue will be addressed later.
