relax contraint on adding AddrMapEntry to AddrMap ( #248 )
...
now you can add them in any order. there's an explicit check at the end to figure out whether there are overlapping regions.

tilelink2: AddressSet always has an assigned base address
...
The consensus seems to be that TileLink should not be assigning
addresses dynamically. The reasons:
1. We can come up with another scheme for assigning addresses that is
independent of TileLink. This decoupling is good, because it would
allow us to use the same mechanism for different buses in the SoC.
2. The informational flow of addresses is more likely to naturally follow
the module hierarchy than the TileLike bus topology. Thus, it seems
better to pass address parameterization using Module constructors.
3. Addresses are still checked by TileLink, so using a Module-centric
flow for addresses will not pose a correctness concern.
4. An address need only be provided to a slave on its construction and
TileLink parameterization spreads this globally. Thus, the burden to
manually assign an address is low.
