mlxsw: spectrum: Add another partition to KVD linear
The KVD linear is currently partitioned into two partitions. One for single entries and another for groups of 32 entries. Add another partition consisting of groups of 512 entries which will allow us to more accurately represent the nexthop weights in non-equal cost multi-path routing.
