It appears to never be used, and clutters things. The new invariant is
that AddrMaps are relative and AddrHashMaps are absolute.

Simplify TileLink Narrower
...
It's not necessary to use addr_beat to determine where to put the Grant
data. Just stripe it across all lanes.
This also gets rid of a dependence on addr_beat in Grant. If we move
towards a regime where TileLink is only narrowed, not widened, we may
be able to drop the field altogether.
