matroxfb: fix incorrect use of memcpy_toio()
commit c81476df1b4241aefba4ff83a7701b3a926bd7ce upstream.
Screen is completely corrupted since 2.6.34. Bisection revealed that it's
caused by commit 6175ddf06b61720 ("x86: Clean up mem*io functions.").
H. Peter Anvin explained that memcpy_toio() does not copy data in 32bit
chunks anymore on x86.
