realtek: pcs: rtl931x: don't mess with autoneg

Part of the configuration sequence for 1G operation can be identified as
setting autonegotiation to enabled for that mode. Starting from a previous
commit, this is being handled properly in the set_autoneg implementation.
Thus, remove that part from the sequence which doesn't make sense there
anymore and might just cause problems.
