tools/testing/nvdimm: add mock acpi_nfit_flush_address entries to nfit_test
In preparation for fixing the BLK path to properly use "directed pcommit" enable the unit test infrastructure to emit mock "flush" tables. Writes to these flush addresses trigger a memory controller to flush its internal buffers to persistent media, similar to the x86 "pcommit" instruction.
