[PATCH v7 3/7] power: supply: bq257xx: Make the default current limit a per-chip attribute

[Alexey Charkov <alchark@flipper.net>]

Add a field for the default current limit to the bq257xx_info structure and
use it instead of the hardcoded value in the probe function.

This prepares the driver for allowing different electrical constraints for
different chip variants.
