This is a board-specific property and determined by the CLM blob firmware provided by the hardware vendor. However, in some cases the firmware will also use ISO3166 country codes internally, and the revision will always be zero. This implies a trivial mapping: cc -> { cc, 0 }. For such cases, add an optional property brcm,ccode-map-trivial which obviates the need to describe every trivial country code mapping in the device tree with the existing brcm,ccode-map property. The new property is subordinate to the more explicit brcm,ccode-map property.
