Input: da9063 - simplify obtaining OF match data
Simplify probe() by replacing of_match_node() for retrieving match data by
device_get_match_data().
Some minor cleanups:
* Remove the trailing comma in the terminator entry for the OF
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.
* Arrange variables in reverse xmas tree order in probe().
