ixgbe: recognize 1000BaseLX SFP modules as 1Gbps

BugLink: https://bugs.launchpad.net/bugs/1837161
[ Upstream commit a8bf879af7b1999eba36303ce9cc60e0e7dd816c ]

Add the two 1000BaseLX enum values to the X550's check for 1Gbps modules,
allowing the core driver code to establish a link over this SFP type.

This is done by the out-of-tree driver but the fix wasn't in mainline.

Fixes: 6a14ee0cfb19 ("ixgbe: Add X550 support function pointers")
