Subject: mlxsw: Set port split ability attribute in driver
Patch-mainline: v5.9-rc1
Git-commit: 1b604efb6c28902df306fce610fba761e9c056d2
References: bsc#1176774

Currently, port attributes like flavour, port number and whether the port
was split are set when initializing a port.

Set the split ability of the port as well, based on port_mapping->width
field and split attribute of devlink port in spectrum, so that it could be
easily passed to devlink in the next patch.
