soc/intel/broadwell/pch: Drop device NVS remainders

Now that device NVS is no longer used as such, stop using it to store
ACPI device settings consumed by the SSDT generator. Instead, provide
the get_acpi_device_state() function to allow saving ACPI device BARs
and activation state from other compilation units. Also, introduce an
enum and a struct to ease handling device state.

Tested on out-of-tree Compal LA-A992P, SerialIO SSDT does not change.
