Introduce a config whether dock is inited in romstage or not

Instead of depending on exact mobo configure general characteristic whether
dock is configured in romstage or ramstage.

X60 and T60 have superio in dock so it needs to be inited to get serial, so
it should be inited in romstage.

On X201 there is nothing useful that early in boot but it's needed to init more
to get dock working, in particular EC init needs to be done first.
