====================
mlxsw: spectrum_router: Optimize LPM trees

Ido says:

This set tries to optimize the structure of the LPM trees used for route
lookup by avoiding lookups that are guaranteed not to return a result.
This is done by making sure only used prefix lengths are present in the
tree.

First two patches are small preparatory steps towards the actual change
in the last patch.
