Subject: [PATCH] platform/x86: dell-lis3lv02d: Add Latitude 5500

Add 0x29 as the accelerometer address for the Dell Latitude 5500 to
lis3lv02d_devices[].

The address was verified as below:

    $ cd /sys/bus/pci/drivers/i801_smbus/0000:00:1f.4
    $ ls -d i2c-?
    i2c-2
    $ sudo modprobe i2c-dev
    $ sudo i2cdetect 2
    WARNING! This program can confuse your I2C bus, cause data loss and worse!
    I will probe file /dev/i2c-2.
    I will probe address range 0x08-0x77.
    Continue? [Y/n] Y
