From: Tobias Jakobi <tjakobi@xxxxxxxxxxxxxxxxxxxxx>
We currently have large switch-statements in all functions that
write to EC registers, even though the bulk of the supported
devices functions more or less the same.
Factor the device-specific data out into a struct oxp_config. This
only leaves logic in the corresponding functions and should make
adding future devices much easier and less error-prone.
Also introduce struct oxp_data which is going to be used in a
later commit to cache device state.
