Subject: [PATCH 3/6] arm64: dts: rockchip: fixes ethernet for 100ASK DshanPi A1

Currently, Ethernet is unusable due to an incorrect PHY address.
This commit fixes this, removes the incorrect 25M clock pinctrl,
and adds the missing PHY supply.

Fixes: d809417c5a40 ("arm64: dts: rockchip: add DTs for 100ASK DShanPi A1")
