[net-next,3/4] ixgbe: move IXGBE_ALLOW_RELAXED_ORDER from architecture to driver

The Relaxed Ordering is an specific PCI option and impact some
architecture performance just like SPARC and ARM64, so compare to
drop this to the several architecture folder, put it in driver looks
more appropriate, it will not impact or be seen for other architectures.
