Xserver/fb: Drop fbmmx.[ch] files and code passages wrapped-in by USE_MMX macro.

 commit 78179ae827bb5d19abb1340084362bc51ad5c1e5
 Author: Søren Sandmann Pedersen <sandmann@redhat.com>
 Date:   Mon Jun 11 22:46:42 2007 -0400

    Remove fbmmx.[ch] files

 Backported-to-NX-by: Mike Gabriel <mike.gabriel@das-netzwerkteam.de>

 Other than X.org, we don't yet introduce using pixman_* function calls
 in the nxagent Xserver's fb code.

 Fixes ArcticaProject/nx-libs#252.
