[PATCH 1/2] arm64: configs: Select REALTEK_PHY as built-in

[PATCH 1/2] arm64: configs: Select REALTEK_PHY as built-in

[Fabio Estevam]

On the i.MX8MP EVK board there is a RTL8211 EThernet PHY and
a typical use case is to boot via NFS. In this case the Ethernet
PHY driver needs to be built-in, so select the driver as built-in
by default.

[PATCH 2/2] arm64: dts: imx8mp-evk: Improve the Ethernet PHY description

[Fabio Estevam]

According to the datasheet RTL8211, it must be asserted low for at least
10ms and at least 72ms "for internal circuits settling time" before
accessing the PHY registers. 

Add properties to describe such requirements.
