[ Upstream commit b726ddf984a56a385c9df406a66c221f3a77c951 ]

Currently when a user uses "devlink dev info", the fw.mgmt.api will be
the major.minor numbers as shown below:

devlink dev info pci/0000:3b:00.0
pci/0000:3b:00.0:
driver ice
serial_number 00-01-00-ff-ff-00-00-00
versions:
fixed:
board.id K91258-000
running:
fw.mgmt 6.1.2
fw.mgmt.api 1.7 <--- No patch number included
fw.mgmt.build 0xd75e7d06
fw.mgmt.srev 5
fw.undi 1.2992.0
fw.undi.srev 5
fw.psid.api 3.10
fw.bundle_id 0x800085cc
fw.app.name ICE OS Default Package
fw.app 1.3.27.0
fw.app.bundle_id 0xc0000001
fw.netlist 3.10.2000-3.1e.0
fw.netlist.build 0x2a76e110
stored:
fw.mgmt.srev 5
fw.undi 1.2992.0
fw.undi.srev 5
fw.psid.api 3.10
fw.bundle_id 0x800085cc
fw.netlist 3.10.2000-3.1e.0
fw.netlist.build 0x2a76e110

There are many features in the driver that depend on the major, minor,
and patch version of the FW. Without the patch number in the output for
fw.mgmt.api debugging issues related to the FW API version is difficult.
Also, using major.minor.patch aligns with the existing firmware version
which uses a 3 digit value.

Fix this by making the fw.mgmt.api print the major.minor.patch
versions. Shown below is the result:

devlink dev info pci/0000:3b:00.0
pci/0000:3b:00.0:
driver ice
serial_number 00-01-00-ff-ff-00-00-00
