[PATCH v3 039/129] net/ice/base: adapt No FEC in Auto support check to add E82X devices

[Anatoly Burakov]

From: Eric Joyner <eric.joyner at intel.com>

Previously, the "No FEC in Auto mode" feature was added to the link management
engine (part of firmware) for E810 devices, and was unsupported at the time on
E82X devices. However, this support is now being extended to new FW versions for
E82X devices, and so the SW check to enable this mode must be changed to allow
E82X devices as well.

Importantly, to support this, modify the existing the ice_is_fw_min_ver()
function to no longer check FW Major/Minor/Patch versions across branches, since
features land in the E810 and E82X branches in different versions. Then, the
check in ice_fw_supports_fec_dis_auto() can check the supported versions in each
branch separately. ice_is_fw_min_ver() is only used in this function, so there's
no behavior change needed elsewhere.
