[PATCH] matroxfb: Use CACHEFLUSH on all chips

Use the CACHEFLUSH register on all chip types.  The register is listed in all
other specs except 2064W.  However I have verified that the register does work
on a 2064W despite being marked reserved in the specs.  There were no
noticeable side effects after writing to the register.
