[PATCH v2 10/11] ARM: dts: stm32: add ethernet1 and ethernet2 for STM32MP135F-DK board

[Christophe Roullier]

Add dual Ethernet:
-Ethernet1: RMII with crystal
-Ethernet2: RMII without crystal
PHYs used are SMSC (LAN8742A)

With Ethernet1, we can performed WoL from PHY instead of GMAC point
of view.
(in this case IRQ for WoL is managed as wakeup pin and configured
in OS secure).
