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.
