arm64: dts: lx2160a-cex7: increase at8035 PHY gigabit Tw parameter
Increase the SmartEEE Tw parameter for Atheros PHYs to stop gigabit links from sporadically dropping. Testing on this platform shows that a value of 24 results in a stable link, whereas 23 or below has the occasional drop. Tested with a Netgear GS116 unmanaged switch link partner with Cat 5e cabling.
