Subject: [PATCH] platform/x86: dell-lis3lv02d: Add Latitude E6530

Add 0x29 as the accelerometer address for the Dell Latitude E6530 to
lis3lv02d_devices[].

The address was verified as below:

    $ cd /sys/bus/pci/drivers/i801_smbus/0000:00:1f.3
    $ ls -d i2c-*
    i2c-20
    $ sudo modprobe i2c-dev
    $ sudo i2cdetect 20
    WARNING! This program can confuse your I2C bus, cause data loss and worse!
    I will probe file /dev/i2c-20.
    I will probe address range 0x08-0x77.
    Continue? [Y/n] Y
