Thomas Richard 851e7f77e4 stm32: add new stm32 target
New stm32 target introduces support for stm32mp1 based devices.
For now it includes an initial support of the STM32MP135F-DK device.
The specifications bellow only list supported features.

Subject: [PATCH 3/5] 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.
Add analog gpio pin configuration ("sleep") to manage power mode on
stm32mp13.
