i2c_new_device() with lis3lv02d for i801 i2c bus needs to be called
after initializing i2c-i801 bus driver.

I have no idea how to do it (properly) outside of i2c-i801.c file.

Same thing is done for Fujitsu machines, see function
i801_probe_optional_slaves() in i2c-i801.c file. So I did similar
approach for Dell machines.
