[RFC] device: Introduce new method for setting device states

We mostly use the same mechanism for setting the state of internal
devices, but we copy it over again and again. Thus, introduce a new
method trying to reduce redundant code.

Basically, this uses an array of structs containing the DEVFN number,
its corresponding FSP option and an indicator if the FSP option is
inverted. The struct maps the device to its related FSP option and
`set_dev_state_by_devicetree()` iterates over the array using the usual
mechanism.

Unresolved issues:
- Where should fspdevmap{.c,.h} be implemented?

Tested in combination with CB:52835 and roda/rw14. Works.
