Your subject suggests this is pensando-elbasr but you write everywhere
pensando-ctrl. Confusing. Pick one.

Drop 'contains'. That's not a correct syntax here.

Drop, not needed.

allOf with ref to spi-peripheral-props.yaml

This is not correct without allOf (should be additionalProperties if you
are not using allOf), which leads you to the missing allOf.

Drop num-cs, not important in this context.
