soc/intel/broadwell/pch: Replace ACPI device NVS

The same functionality can be provided through a runtime-generated SSDT.
The remaining parts of device NVS are removed in a follow-up.

Since the SSDTs are only loaded after the DSDT (if loaded at all), using
SSDT-provided objects outside method bodies is not possible: the objects
are not yet in OSPM's ACPI namespace, which causes in ACPI errors. Owing
to this, the operation regions used by the _PS0 and _PS3 methods need to
be moved into the SSDT, as they depend on the SSDT-provided BAR1 values.

Tested on out-of-tree Compal LA-A992P, generated SSDT disassembles with
no errors and contains expected values. Linux does not complain either.
