[PATCH v2] ARM: dts: stm32: Add ethernet support for DH STM32MP13xx DHCOR DHSBC board

[Marek Vasut <marex@denx.de>]

Add ethernet support for the DH STM32MP13xx DHCOR DHSBC carrier board.
This carrier board is populated with two gigabit ethernet ports and two
Realtek RTL8211F PHYs, both are described in this DT patch.
