Originally NVDIMM Label methods was defined in Intel PMEM _DSM Interface
Spec [1], of function index 4, 5 and 6.
Recent ACPI spec [2] has deprecated those _DSM methods with ACPI NVDIMM
Label Methods _LS{I,R,W}. The essence of these functions has no changes.

This patch set is to update QEMU emulation on this, as well as update
bios-table-test golden binaries.

[1] Intel PMEM _DSM Interface Spec v2.0, 3.10 Deprecated Functions

[2] ACPI Spec v6.4, 6.5.10 NVDIMM Label Methods

Change Log:
v2 --> v3:
Patch of nvdimm_debug() --> qemu trace, has been separated and already
upstream'ed.
Patch of accepting _DSM rev.2 is dropped, as unnecessary.
Roll back implementation to the idea of simply wrapper _DSM.

v1 --> v2:
Almost rewritten
Separate Patch 2
Dance with tests/qtest/bios-table-tests
Add trace event
