Remove two features that have been reported to cause problems with
certain variants of the NCR chip from FE_CACHE_SET: FE_CLSE (enable
cache-line size register) and FE_ERMP (enable read-multiple). They
will be re-enabled, if a fix for the underlying problem (a restriction
in the memory to memory move logic of some chips) has been implemented.
