x86, kexec, nvdimm: Use walk_iomem_res_desc() for iomem search
Change the callers of walk_iomem_res() scanning for the
following resources by name to use walk_iomem_res_desc()
instead.
"ACPI Tables"
"ACPI Non-volatile Storage"
"Persistent Memory (legacy)"
"Crash kernel"
Note, the caller of walk_iomem_res() with "GART" will be removed
in a later patch.
