[PATCH 1/1] UBUNTU: SAUCE: net: atlantic: Add support for firmware v4

BugLink: https://bugs.launchpad.net/bugs/1886908

We have a new ethernet card that is supported by the atlantic driver:
01:00.0 Ethernet controller [0200]: Aquantia Corp. AQC107 NBase-T/IEEE 802.3bz Ethernet Controller [AQtion] [1d6a:07b1] (rev 02)

But the driver failed to probe the device:
kernel: atlantic: Bad FW version detected: 400001e
kernel: atlantic: probe of 0000:01:00.0 failed with error -95

As a pure guesswork, simply adding the firmware version to the driver
can make it function. Doing iperf3 as a smoketest doesn't show any
abnormality either.
