igc: Remove stale comment about Tx timestamping

[ Upstream commit 47ce2956c7a61ff354723e28235205fa2012265b ]

The initial igc Tx timestamping implementation used only one register for
retrieving Tx timestamps. Commit 3ed247e78911 ("igc: Add support for
multiple in-flight TX timestamps") added support for utilizing all four of
them e.g., for multiple domain support. Remove the stale comment/FIXME.
