pci-properties: add properties to enable hotplug for spapr

drmgr expects ibm,my-drc-index and ibm,loc-code OF properties in
the corresponding device tree node to determine whether a
pre-populated slot is hotpluggable/unpluggable. This is also
stated as a boot-time requirement for DR-capable devices in SPAPR,
though it does not specify there how these entries are to be generated.

In the case of QEMU, hotpluggable slots are allocated entries based on
bus/slotno values, so we can determine these entries statically at
boot-time, rather than relying on RTAS calls as we would during
OS-driven configuration.
