Add support for configuring devlink port splitting from network device
sections using a device split option, e.g.:
config device
option name 'swp1'
option split '4'
Gate the feature behind DEVLINK_PORT_SPLIT so it stays out of normal
builds unless explicitly enabled.

Add support for configuring devlink port splitting from network device
sections using a device split option, e.g.:
Port splitting is commonly used on network switches where a front panel
port can be split into multiple links with a breakout cable.
The feature is disabled by default to minimize overhead on other device/targets
and can be enabled with
CONFIG_NETIFD_DEVLINK_PORT_SPLIT.Run tested on a Mellanox Spectrum SN3420.
