mlxsw: Introduce initial Spectrum-2 support

This patch set adds initial support for the Spectrum-2 ASIC. The first
two patches add Spectrum-2 specific KVD linear (KVDL) manager. Unlike
the Spectrum ASIC, there is no linear memory and instead the type of the
entry (e.g., nexthop) and its index are hashed and the entry is placed
in the computed address in the hash-based KVD memory.

The third patch adds Spectrum-2 stubs in the multicast routing code.
Support for multicast routing will be added later on.

Patches 4-15 add ACL support. The Spectrum-2 ASIC includes an
algorithmic TCAM (A-TCAM) and a regular circuit TCAM (C-TCAM) for rules
that can't be inserted into the A-TCAM. This set does not make use of
the A-TCAM and only places rules in the C-TCAM. This provides equivalent
scale and performance to the Spectrum ASIC. A follow-up patch set will
introduce A-TCAM support.

The last patch extends the main driver file to work with both ASICs.
