tools/testing/nvdimm: fix allocation range for mock flush hint tables
Commit 480b6837aa57 "nvdimm: fix PHYS_PFN/PFN_PHYS mixup" identified
that we were passing an invalid address to devm_nvdimm_ioremap(). With
that fixed it exposed a bug in the memory reservation size for flush
hint tables. Since we map a full page we need to mock a full page of
memory to back the flush hint table entries.
