devlink: Add a generic wake_on_lan port parameter 



wake_on_lan - Enables Wake on Lan for this port. If enabled,
the controller asserts a wake pin based on the WOL type.

v2->v3:
- Define only WOL types used now and define them as bitfield, so that
  mutliple WOL types can be enabled upon power on.
- Modify "wake-on-lan" name to "wake_on_lan" to be symmetric with
  previous definitions.
- Rename DEVLINK_PARAM_WOL_XXX to DEVLINK_PARAM_WAKE_XXX to be
  symmetrical with ethtool WOL definitions.
