mfd: da9062: Simplify obtaining I2C match data
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.
