    mtd: spi-nor: enable stateless 4b op codes for mx25u25635f
    
    All required stateless 4-byte op codes are supported by this flash
    chip. The stateless 4-byte support can't be autodetected due to a
    missing 4-byte Address Instruction Table in SFDP.
    
    Fixes hangs on reboot for SoCs expecting the flash chip in 3byte mode.
