[Qemu-ppc] [PATCH v3 0/4] pc-dimm: pre_plug "slot" and "addr" assignment

[David Hildenbrand]

As requested by Igor, assign and verify "slot" and "addr" in the
pre_plug handler. Factor out the compatibility handling/configuration
for detecting the alignment to be used when searching for an address
in guest physical memory for a memory device.

This is another part of the original series
    [PATCH v4 00/14] MemoryDevice: use multi stage hotplug handlers

This refactoring is the last step before factoring out pre_plug, plug and
unplug logic of memory devices completely into memory-device.c

v2 -> v3:
- "util/oslib-win32: indicate alignment for qemu_anon_ram_alloc()"
-- take allocation granularity into account
-- drop comment
- "pc-dimm: assign and verify the "addr" property during pre_plug"
-- compat_align -> legacy_align
-- shortened align detection as proposed by Igor
-- trace address asignment in pre_plug

v1 -> v2:
- dropped "machine: factor out enforce_aligned_dimm into memory_device_align"
- dropped "pc-dimm/memory-device: detect alignment internally"
- added "util/oslib-win32: indicate alignment for qemu_anon_ram_alloc()"
-- indicate the alignment and therefor simplify compat handling for
   Windows as we can ...
- added "pc: drop memory region alignment check for 0"
-- ... drop a check for memory_region_get_alignment(mr), allowing us to
   factor out compat handling for pc DIMM/NVDIMM alignment in a clean way.
- "pc-dimm: assign and verify the "addr" property during pre_plug"
-- Default to "memory_region_get_alignment(mr)" if no compat alignment
   has been specified.
