Subject: [RFC 3/9] PCI/portdrv: create platform devices for child OF nodes

In order to introduce PCIe power-sequencing, we need to create platform
devices for child nodes of the port driver node. They will get matched
against the pwrseq drivers (if one exists) and then the actuak PCIe
device will reuse the node once it's detected on the bus.
