fix(stm32mp15-fdts): use /omit-if-no-ref/ for spi and i2c
Use /omit-if-no-ref/ keyword in DT to remove extra device nodes only
when they are not used / not referenced.
If the board device tree only defines subnodes, dtc does not consider it
as usage, you have to specifically mention device's phandle, e.g.:
\ {
i2c6-phandle = <&i2c6>;
};
or in aliases section
aliases {
i2c6 = &i2c6;
};
