Merge branch 'mlxse-resource-query'

Jiri Pirko says:

====================
mlxsw: Replace Hw related const with resource query results

Nogah says:

Many of the ASIC's properties can be read from the HW with resources query.
This patchset adds new resources to the resource query and implement
using them, instead of the constants that we currently use.
Those resources are lag, kvd and router related.
====================
