Simplify probe() by replacing of_device_get_match_data() and ID lookup for
retrieving match data by i2c_get_match_data().

Some minor cleanups:
 * Remove the trailing comma in the terminator entry for the ID
   table making code robust against (theoretical) misrebases or other
   similar things where the new entry goes _after_ the termination without
   the compiler noticing.
 * Move OF table near to the user.
