Subject: [PATCH v2 10/12] ARM: dts: stm32: add ethernet1/2 RMII pins for STM32MP13F-DK board

Those pins are used for Ethernet 1 and 2 on STM32MP13F-DK board.
ethernet1: RMII with crystal.
ethernet2: RMII without crystal.
PHYs used are SMSC (LAN8742A)
Add analog gpio pin configuration ("sleep") to manage power mode on
stm32mp13.
