[ Upstream commit a5b9fdd33c59a964a26d12c39b636ef85a25b074 ]

Add accelerometer address 0x29 for Dell Latitude 5400.

The address is verified as below:

$ cat /sys/class/dmi/id/product_name
Latitude 5400

$ grep -H '' /sys/bus/pci/drivers/i801_smbus/0000\:00*/i2c-*/name
/sys/bus/pci/drivers/i801_smbus/0000:00:1f.4/i2c-10/name:SMBus I801 adapter at 0000:00:1f.4

$ i2cdetect 10
