Subject: [PATCH 5.14 039/125] arm64: dts: imx8mm-kontron: Fix connection type for VSC8531 RGMII PHY

From: Frieder Schrempf <frieder.schrempf@...tron.de>

commit 0b28c41e3c951ea3d4f012cfa9da5ebd6512cf6e upstream.

Previously we falsely relied on the PHY driver to unconditionally
enable the internal RX delay. Since the following fix for the PHY
driver this is not the case anymore:

commit 7b005a1742be ("net: phy: mscc: configure both RX and TX internal
delays for RGMII")

In order to enable the delay we need to set the connection type to
"rgmii-rxid". Without the RX delay the ethernet is not functional at
all.
