[Qemu-devel] [PATCH v2] pc-dimm: use same mechanism for [get|set]_addr

[Wei Yang <richardw.yang@linux.intel.com>]

[get|set]_addr are two counterpart to access PCDIMMDevice.addr.

Since we have already set up a property PC_DIMM_ADDR_PROP for this
field and use this mechanism in set_addr, it would be more proper to use
the same mechanism in get_addr.

This patch uses object_property_get_uint() to replace the direct memory
access to make [get|set]_addr with the same mechanism.
