Subject: [PATCH v2 1/3] dt-bindings: add imx8mp-libra-rdk-fpsc

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 imx8mp-phycore-som
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.
