Register devlink_port with devlink and create initial port params
table for bnxt_en. The table consists of a generic parameter:
wake-on-lan: Enables Wake on Lan for this port when magic packet
is received with this port's MAC address using ACPI pattern.
If enabled, the controller asserts a wake pin upon reception of
WoL packet. ACPI (Advanced Configuration and Power Interface) is
an industry specification for the efficient handling of power
consumption in desktop and mobile computers.
