The 'unevaluatedProperties' schema checks is not fully working and doesn't
catch some cases where there's a $ref to another schema. A fix is pending,
but results in new warnings in examples.

The Apple PCIe host schema is missing 'power-domains' in the schema.
The example has 3 power domains. However, this is wrong too as actual
dts files have a single power domain and Sven confirmed 1 is correct.

v2:
 - Correct the power-domains to be 1 and update the example
