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.

The new version supports two features that are required by upcoming
changes in the driver:
* Querying of new resources allowing port split into two ports on
Spectrum-2 systems
* Querying of number of gearboxes on supported systems such as SN3800

Since the number of local ports in 4x changed between SPC and SPC-2,
firmware expose new resources that the driver can query.

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.
