[U-Boot] [PATCH] arm: dts: Stratix10: change pad skew values for EMAC0 PHY driver

[Ooi, Joyce]

The HPS EMAC0 drive strength is changed to 4mA because the initial 8mA
drive strength has caused CE test to fail. This requires changes on the
pad skew for EMAC0 PHY driver. Based on several measurements done, Tx
clock does not require the extra 0.96ns delay which was needed in
Arria10.
