igb: extend PTP timestamp adjustments to i211

[ Upstream commit 0bb7b09392eb74b152719ae87b1ba5e4bf910ef0 ]

The i211 requires the same PTP timestamp adjustments as the i210,
according to its datasheet. To ensure consistent timestamping across
different platforms, this change extends the existing adjustments to
include the i211.

The adjustment result are tested and comparable for i210 and i211 based
systems.
