Actually, I wonder if we should not just put the hwmon driver
capabilities directly into the mxs-lradc driver, just like it's already
been done in this driver for the touchscreen support.

The probing of this hwmon driver doesn't really belong to the DT, it's
not really realistic to probe it from the machine definition, and it
really is the IP that is wired that way.
