pinctrl: lynxpoint: Keep pointer to struct device instead of its container

Browse Source 
There is no need to keep pointer to struct platform_device, which is container
of struct device, because the latter is what have been used everywhere outside
of ->probe() path. In any case we may derive pointer to the container when
needed.
