Merge branch 'devlink-unknown'

Simon Horman says:

====================
devlink: add unknown 'fw_load_policy' value

Dirk says:

Recently we added an unknown value for the 'reset_dev_on_drv_probe' devlink
parameter. Extend the 'fw_load_policy' parameter in the same way.

The only driver that uses this right now is the nfp driver.
