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.
