    mtd: jedec_probe: fix NEC uPD29F064115 detection
    
    linux v2.6.31-rc6 can not detect NEC uPD29F064115.
    
    uPD29F064115 is a 16 bit device.
    datasheet:
      http://www.cn.necel.com/memory/cn/download/M16062EJ2V0DS00.pdf
    
    This applies the same fix as used for SST chips in commit
    ca6f12c67ed19718cf37d0f531af9438de85b70c ("jedec_probe: Fix SST 16-bit
    chip detection").
