Change to call walk_iomem_res_desc() for searching resource entries
with the following names:
"ACPI Tables"
"ACPI Non-volatile Storage"
"Persistent Memory (legacy)"
"Crash kernel"
Note, the caller of walk_iomem_res() with "GART" is left unchanged
because this entry may be initialized by out-of-tree drivers, which
do not have 'desc' set to IORES_DESC_GART.
