Changed

• nRF53 and nRF91 Series: Improved the UICR handling when using the ERASE_RANGES_TOUCHED_BY_FIRMWARE option in nrfutil device program. This previously required the UICR value on the device to be 0xFF before proceeding, but this blocked the cases where the UICR value to write was unchanged, or when the flash memory could still be written from the previous value to the new value. This no longer errors out on nRF53 and nRF91 if it is possible to write the UICR data.

This still errors out on nRF54L Series devices because of the write-once lock, which will cause the write to fail in any case. The UICR erase is used for nRF52 Series devices.
