configs/octavo_osd32mp1_brk: new defconfig

This patch adds support to Octavo Systems BRK board. We use the TF-A,
U-Boot and Linux versions from ST, Device Trees from Octavo as well as
a U-Boot patch from Octavo.

Reference:

    https://octavosystems.com/octavo_products/osd32mp1-brk/

The device tree blobs come from Octavo System:

    https://github.com/octavosystems/OSD32MP1-BRK-device-tree.git

The uboot patches come from Octavo System:

+OSD32MP1-BRK
+
+Intro
+=====
+
+This configuration supports the OSD32MP1-BRK platform:
+
+  https://octavosystems.com/octavo_products/osd32mp1-brk/
+
+How to build
+============
+
+ $ make octavo_osd32mp1_brk_defconfig
+ $ make
+
+How to write the microSD card
+=============================
+
+Once the build process is finished you will have an image called
+"sdcard.img" in the output/images/ directory.
+
+Copy the bootable "sdcard.img" onto an microSD card with "dd":
+
+  $ sudo dd if=output/images/sdcard.img of=/dev/sdX
+
+Boot the board
+==============
+
+ (1) Insert the microSD card.
+
+ (2) Plug an USB-SERIAL cable on the RX, TX and GND pins
+
+ (3) Plug a micro-USB cable to power-up the board.
+
+ (4) The system will start, with the console on UART.
