Kory Maincent 672807b815 configs/octavo_osd32mp1_red: new defconfig 
This patch adds support for the Octavo Systems RED 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-red/

The device tree blobs come from Octavo System:

  https://github.com/octavosystems/OSD32MP1-RED-Device-tree.git

The uboot patches come from Octavo System:
