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. This changes the reference from snps,dw-pcie.yaml to snps,dw-pcie-common.yaml, since the interrupts are vendor specific and should not be listed in the generic file. The only other bit from the generic binding are the reg-names, which are overwritten by this binding.
