regulator: ltc3589: Convert enum->pointer for data in the match tables

Browse Source 
Convert enum->pointer for data in the match tables, so that the hw
differences can be stored in pointer and there by simpily the code.

Add struct ltc3589_info for hw differences between the devices and replace
ltc3589_variant->ltc3589_info for data in the match table. Simplify the
probe() by replacing of_device_get_match_data() and ID lookup for
retrieving data by i2c_get_match_data(). Drop enum ltc3589_variant and
variant from struct ltc3589_info as there are no users.

While at it, dropped trailing comma in the terminator entries for ID
table.
