Subject: [PATCH] arm64: dts: allwinner: a64: pine64-plus: Add PHY regulator
delay
Depending on kernel and bootloader configuration, it's possible that
Realtek ethernet PHY isn't powered on properly. It needs some time
before it can be used.
Fix that by adding 100ms ramp delay to regulator responsible for
powering PHY.
Fixes: 94dcfdc77fc5 ("arm64: allwinner: pine64-plus: Enable dwmac-sun8i")
