Drop, core schema has it. Unless you wanted the interrupts to require

additionalProps, see other bindings.

But OTOH, if this is SPI device then where is spi-peripheral-props
reference (and then unevaluatedProps woyld be correct), regardless if
you tested drivers or not.

Let's drop the website? No need to repeat it for every driver.
