Retire snd_mss ISA sound card driver
The snd_mss driver supported Microsoft Sound System sound cards.
ISA sound card drivers are deprecated as discussed on the current[1] and
stable[2] mailing lists. Deprecation notices were added in e39ec8933be4
and MFCd to stable branches.
Driver removals are being committed individually so that specific
drivers can be restored if necessary (either in FreeBSD or by downstream
projects).
