power: supply: bq24190: Add BQ24297 support

The BQ24297 is identical to the BQ24296 except that it uses USB D+ / D-
data-lines for charger-type (max. input-current) detection instead of
a PSEL input pin.

This is the same difference as between the already supported BQ24190
(D+ / D-) and the BQ24192 (PSEL).

Note just like with the BQ24190 vs BQ24192 there is no difference how
the charger-IC works at the register-level. The only difference is in
the external hardware interface.
