The lm90 doesn't support device tree very well. In the DT, we need to
named as "lm90" so that the lm90 driver can be loaded, and we also need
to add "nct1008" to indicate this is the nct1008 device, so that the
lm90 driver can be loaded with the right i2c_device_id->driver_data.

I set the " compatible = "lm90,nct1008" ", this is the simplest way, and
we doesn't need to change the lm90.c.

Thanks.
