drivers/xpowers/axp209: Adapt to new I²C API

Originally, axp209_(read|write) accessors relied on i2c_(read|write)
to return the number of bytes transferred. This was changed in
* cdb61a6 i2c: Replace the i2c API.
to return an error code or 0 on success. This caused the AXP209 check
to fail. Fix the accessors to account for this new behavior.
