====================
mlxsw: Firmware version update

This patchset updates mlxsw to use a new firmware version and adds
support for split into two ports on Spectrum-2 based systems.

Patch #1 updates the firmware version to 13.2000.1122

Patch #2 queries new resources from the firmware.

Patch #3 makes use of these resources in order to support split into two
ports on Spectrum-2 based systems. The need for these resources is
explained by Shalom:

When splitting a port, different local ports need to be mapped on different
systems. For example:

SN3700 (local_ports_in_2x=2):
  * Without split:
      front panel 1   --> local port 1
      front panel 2   --> local port 5
  * Split to 2:
      front panel 1s0 --> local port 1
      front panel 1s1 --> local port 3
      front panel 2   --> local port 5

SN3800 (local_ports_in_2x=1):
  * Without split:
      front panel 1 --> local port 1
      front panel 2 --> local port 3
  * Split to 2:
      front panel 1s0 --> local port 1
      front panel 1s1 --> local port 2
      front panel 2   --> local port 3

The local_ports_in_{1x, 2x} resources provide the offsets from the base
local ports according to which the new local ports can be calculated.
