As the PCIe driver is updated in kernel 4.10, and it will read the PCIe resource in the PCIe device, so the resource description should also be put into the Device(PCIx).
- add _OSC support
- put the pcie resource description into the Device(PCIx), in order to compatible with kernel 4.10 PCIe driver.
Changes are smaller in this file but same comment as #12
