imx8mp-libra-rdk-fpsc is a development board based on the phyCORE-i.MX
8M Plus FPSC SoM. Add its description and binding. The
imx8mp-phycore-fpsc som differs from the existing phyCORE-i.MX 8M Plus
(dts: imx8mp-phycore-som.dtsi) in its physical form regarding the ball
grid array. Other differences between the SoMs are missing SPI-NOR on
this SoM and 1.8V IO voltage instead of 3.3V as found on the existing
imx8mp-phycore-som. As a result the imx8mp-phycore-som is not compatible
with this new libra development board.

See https://patchwork.ozlabs.org/project/devicetree-bindings/patch/20250417-wip-y-moog-phytec-de-imx8mp-phycore-fpsc-v3-1-ccb885b38ffd@phytec.de

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
