Airoha partition table follow normal fixed-partition implementation with a special implementation for the ART partition. This is always the last partition and is placed from the end of the flash - the partition size. To enable this special implementation for ART partition, the relevant node require the "airoha,dynamic-art" compatible. With that declared, offset value is ignored and real offset is updated with the calculated value. Due to usage of specific bad block management driver, the MTD size might vary hence the ART partition offset needs to be dynamically parsed and can't be declared statically.
