[Qemu-devel] [RFC PATCH v0 1/2] pc-dimm: Make pc_dimm_built_list() global

[Bharata B Rao <bharata@linux.vnet.ibm.com>]

Making pc_dimm_built_list() global allows other parts of QEMU code
to build and walk through the DIMM list in address-sorted order.

This is needed in the next patch for sPAPR code to create
ibm,dynamic-memory-v2 device tree property that will have entries
for populated DIMMs as well as available hotpluggable areas.

CHECK: List of DIMMs is already available via qmp_pc_dimm_device_list(),
but that doesn't provide a sorted list.
