For example the "legacy" interrupt combines "inta/intb/intc/intd" with a register providing the details. Currently the binding is not specifying these interrupts resulting in a bunch of errors for all rk356x boards using PCIe. Fix this by specifying the interrupts and add them to the example to prevent regressions.
