[PATCH v2 4/5] arm64: dts: meson: g12a: x96-max: fix PHY deassert timing requirements

[Stefan Agner]

According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
egisters. On similar boards with the same PHY this fixes an issue where
Ethernet link would not come up when using ip link set down/up.
