misc: ad525x_dpot: Add support for SPI module device table matching
Passing device name via platform data, is a leftover from times where
SPI module device table matching was not existent.
* Add id_table and remove old mechanism.
(To my knowledge no intree boards affected)
* Miscellaneous other cleanup.
