Francois Berder 03842c1739 sc16is7xx: always write state when configuring GPIO as an output ...

The regmap_update first reads the IOState register and then triggers
a write if needed. However, GPIOS might be configured as an input so
 the read to IOState on this GPIO is the current state which might
be random.
