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: 's avatarMike 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.
