    baytrail:fix the coding error on PCIe L1 exit lantency
    
    The original code use L1EXIT_MASK to shift the bit for
    PCIe L1 exist lantency, the code should be use
    L1EXIT_SHIFT for bit shift.
    
    BUG=chrome-os-partner:34037
    BRANCH=None
    TEST=build and boot on candy, verify B0:D28:F0 + 4Ch [17:15]
    set to 010b. Correspond WIFI device performance got improvement.
