Deprecate jedec_ts(4) and point users to jedec_dimm(4) instead

Browse Source 
jedec_dimm(4) is a superset of the functionality of jedec_ts(4). Mark
jedec_ts(4) as removed in FreeBSD 12, and include a pointer to the migration
instructions in the jedec_dimm(4) manpage, in both the jedec_ts(4) code and
the jedec_ts(4) manpage. Add a note to the jedec_dimm(4) manpage about the
fact that it is a superset of jedec_ts(4).

This change will be MFCed to stable/11 and stable/10; the followup change
to actually remove jedec_ts(4) from -HEAD will not.
