eth: fbnic: Add devlink firmware version info
This adds support to show firmware version information for both stored and
running firmware versions. The version and commit is displayed separately
to aid monitoring tools which only care about the version.
Example output:
# devlink dev info
pci/0000:01:00.0:
driver fbnic
serial_number 88-25-08-ff-ff-01-50-92
versions:
running:
fw 24.07.15-017

fw.bootloader 24.07.10-000
fw.bootloader.commit hfef3ac835ce7
stored:
