[PATCH] don't use floating point in tdfxfb

From: Jakub Bogusz <qboosh@pld-linux.org>

This patch removes using of floating point operations in tdfxfb - they
are really not needed here (these consts are used only in substitutions
and comparisons with integers) are cause unresolved symbols on some
archs - e.g. on alpha:

*** Warning: "__ltdf2" [drivers/video/tdfxfb.ko] undefined!
*** Warning: "__adddf3" [drivers/video/tdfxfb.ko] undefined!
*** Warning: "__floatsidf" [drivers/video/tdfxfb.ko] undefined!
