fdts: stm32mp1: add support for the Seeed Odyssey SoM and board 



Seeed Studio’s SoM‐STM32MP157C is a System‐on‐Module that integrates the
STM32MP157C MPU (the 650 MHz dual‐core variant with a GPU and a
cryptographic processor) the STPMIC1A PMIC, 512 MB of DDR3 RAM and a
4 GB eMMC. There are two LEDs as well, one hardwired to the PMIC’s VDD
output, and the other available at the MPU’s port PG3. The SoM can be
plugged into a carrier board using its three 70‑pin connectors.

Seeed Odyssey‐STM32MP157C is the reference carrier board for the SoM in
a Raspberry Pi‐like form factor. It features a WiFi/Bluetooth chip, a
microSD card port and various I/O interfaces.

The device tree is based on the DKx boards. TF‑A was successfully tested
on the board with Buildroot 2021.02 and U-Boot 2021.04.
