Provide devlink .info_get callback to allow the driver to report
detailed version information. The following info is reported:

 "serial_number" -> The PCI DSN of the adapter
 "fw.mgmt" -> The version of the firmware
 "fw.mgmt.api" -> The API version of interface exposed over the AdminQ
 "fw.psid" -> The version of the NVM image
 "fw.bundle_id" -> Unique identifier for the combined flash image
 "fw.undi" -> The combo image version

With this, 'devlink dev info' provides at least the same amount
information as is reported by ETHTOOL_GDRVINFO:

$ ethtool -i enp2s0f0 | egrep '(driver|firmware)'
driver: i40e
firmware-version: 9.30 0x8000e5f3 1.3429.0

$ devlink dev info pci/0000:02:00.0
pci/0000:02:00.0:
