svn commit: r248456 - head/sys/dev/sis

[Pyun YongHyeon]

Author: yongari

New Revision: 248456
URL: http://svnweb.freebsd.org/changeset/base/248456

Log:
  r119712 introduced SIS_TYPE_83816 but it was not actually set in
  driver such that checking against the type was always false.
  To detect NS DP83816, driver should have checked silicon revision
  register for NS controllers. While here, remove SIS_TYPE_83816 to
  not make the similar mistake again.
