relative offset and size specified. Depending on partition function extra
properties can be used.
+ A partition may be dynamically allocated by a specific parser at runtime.
+ In this specific case, a specific suffix is required to the node name.
+ Everything after 'partition-' will be used as the partition name to compare
+ with the one dynamically allocated by the specific parser.
+ If the partition contains invalid char a label can be provided that will
+ be used instead of the node name to make the comparison.
+ This is used to assign an OF node to the dynamiccally allocated partition
+ so that subsystem like NVMEM can provide an OF node and declare NVMEM cells.
+ The OF node will be assigned only if the partition label declared match the
+ one assigned by the parser at runtime.
