[ Upstream commit 6168efbebace0db443185d4c6701ca8170a8788d ]
A PCI controller device, e.g., StarFive, is parent to PCI host bridge
device. We must enable runtime PM of the controller before enabling runtime
PM of the host bridge, which will happen in pci_host_probe(), to avoid this
warning:
pcie-starfive 940000000.pcie: Enabling runtime PM for inactive device with active children
Fix this issue by enabling StarFive controller device's runtime PM before
calling pci_host_probe() in plda_pcie_host_init().
