'spi@' is reserved for SPI controllers.

Any new compatibles need to be documented with schema.

This should just be moved into elba-asic-common.dtsi IMO unless you have 
good reasons to keep it separate.

This needs an SoC family schema.

Generally this and 'model' should be in the same file (the board file).
