Subject: [PATCH] arm64: dts: qcom: remove max-speed = 1G for RGMII
 for ethernet

The RGMII interface is designed for speeds up to 1G. Phylink already
imposes the design limits for MII interfaces, and additional
specification is unnecessary. Therefore, we can remove this property
without any effect.
