Per datasheet here[1] mt25qu128 does seem to support CHIP erase. So please drop NO_CHIP_ERASE.
Micron flash ID table is sorted by device ID. Could you insert the entry accordingly?
Also, please limit the line to 80 char like:
{ "mt25qu128", INFO(0x20bb18, 0, 64 * 1024, 1024, SECT_4K |
USE_FSR | SPI_NOR_QUAD_READ) },
