c8b1f0801b Remove start address option from AddrMapEntries
It appears to never be used, and clutters things.  The new invariant is
that AddrMaps are relative and AddrHashMaps are absolute.

356efe2fd5 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.
