xf86-video-ati: fix crash/hang when accel is unavailable + more archs

Previously the ati driver would crash the xserver or hang when hw
accel was unavailable (e.g. via Option "NoAccel" "true"). This has
been fixed with the patch.

Also, remove archs= restrictions because they don't make any sense.

Subject: [PATCH] Don't crash X server if GPU acceleration is not available
Commit d1d8e3c8d0a0a0394d395eba171460501745209b causes X server
to fail on startup when GPU acceleration is not working (or is
disabled). The reason is that `radeon_get_pixmap_bo` function
gets called too early (before EXA has been initialized) and
fails with an assert:

Don't call `exaGetPixmapDriverPrivate` if the acceleration (EXA) is not
enabled [yet] to avoid the problem.
