dt-bindings: PCI: amlogic,axg-pcie: Fix select schema

The amlogic,axg-pcie binding was never enabled as the 'select' schema
expects a single compatible value, but the binding has a fallback
compatible. Fix the 'select' by adding a 'contains'. With this, several
errors in the clock and reset properties are exposed. Some of the names
aren't defined in the common DWC schema and the order of clocks entries
doesn't match .dts files.
