H A Dmeson-gxm-q200.dtsc183c406 Mon Dec 07 11:58:00 CST 2020 Stefan Agner <stefan@agner.ch> arm64: dts: meson: fix PHY deassert timing requirements

According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
registers. This fixes an issue seen on ODROID-C2 where the Ethernet
link doesn't come up when using ip link set down/up:
