Mellanox: Add new mlxsw_spectrum firmware xx.2010.1232

Add latest verified version of Nvidia Spectrum-family switch firmware,
for Spectrum (13.2010.1232), Spectrum-2 (29.2010.1232) and Spectrum-3
(30.2010.1232).

The following bugs were fixed:

- On Spectrum-3, when cut-through forwarding large frames from a 1Gbps port
  to a 100Gbps one, packets would get corrupted.
- Several issues in handling of MPLS on Spectrum-2.
- An issue that caused fast reboot to take longer than 30s.
- An issue with bulk update of FDB where roamed FDB entries were not
  updated.
- Maximum MTU reported for Quantum chips was 4222 bytes instead of 4096.
- Packets wrongly discarded due to egress STP filter when VxLAN is
  configured.
- On Spectrum-2, on 1Gbps or 10Gbps ports, when congestion occurs, packets
  would very rarely get stuck in the chip and cause switch to hang.
- On Spectrum-3, when ECMP has many next hops based on VLAN interfaces
  packets may rarely get a wrong VLAN tag and be dropped.
- On Spectrum-3, effective speed of a 400Gbps port would only be 380Gbps
  with 1500-byte packets.
- On a switch with an external PHY, attempts to configure PFC are no longer
  bounced by FW as unsupported.
- An issue in handling of QinQ packets with EtherType 8100 on Spectrum-3.
- On SN4800, an issue in PCIe gen3 link negotiation instability.
