-    ssb: sprom: add dev_id field for value overriding standard ID
-    
-    Some devices may have different features despite sharing the same ID
-    (e.g. PCI ID). For example 14e4:4331 is usually a dual band, but this
-    can be "limited". Device with "pci/x/y/devid=0x4332" supports 2.4 GHz
-    only. Similarly 0x4333 will mean support for 5 GHz only.
-    Add entry in SPROM so info described above can be extracted and stored.
