8139f71dfb Work around Chisel2 bug

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.
