devlink: Add new "enable_eth" generic device param
Add new device generic parameter to enable/disable creation of
Ethernet auxiliary device and associated device functionality
in the devlink instance.
User who prefers to disable such functionality can disable it using below
example.
$ devlink dev param set pci/0000:06:00.0 \
name enable_eth value false cmode driverinit
$ devlink dev reload pci/0000:06:00.0
At this point devlink instance do not create auxiliary device for the
Ethernet functionality.
