eth: fbnic: Add devlink dev flash support

Browse source

Add support to update the CMRT and control firmware as well as the UEFI
driver on fbnic using devlink dev flash.

Make sure the shutdown / quiescence paths like suspend take the devlink
lock to prevent them from interrupting the FW flashing process.
