ARM: dts: meson: fix PHY deassert timing requirements
[ Upstream commit 656ab1bdcd2b755dc161a9774201100d5bf74b8d ]
According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
registers. 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.
Fixes: a2c6e82e5341 ("ARM: dts: meson: switch to the generic Ethernet PHY reset bindings")
