tridentfb: acceleration code improvements

This patch brings various acceleration improvements:
- set  copyarea/fillrect for non-accelerated framebuffer (fix)
- remove 15 bpp depth handling to simplify code as it hardly
  works (15 bpp handling was obviously missing in some switches)
- add fb_sync call and move waiting before accelerated function
  to make acceleration more asynchronous to cpu (few % of speed
  improvement)
- add cpu_relax() call in waiting loops
- make longer register names and name more registers
- move registers' definition to header
- general code improvements (shortening, simplifying)
