dt: amd-seattle: fix PCIe legacy interrupt routing
The AMD Seattle SOC can be configured to expose up to 3 PCIe root ports, each of which is wired to 4 dedicated SPI wired interrupts for legacy INTx support. Update the SOC DT description to reflect this. Fix a stale comment about the size of the MMIO64 resource window while at it.
