soc/broadwell/acpi.c: Fix unresolvable symbol '\DNVS'
Fixes:
27c51a0 ("Revert "soc/intel/broadwell/pch: Replace ACPI device NVS"")
which reverted the removal of device NVS, but was not boot tested on any
Broadwell Chromebooks. It was recently discovered that the DNVS
object was not being loaded, due to a weak function setting the size
as zero not being defined for the platform/soc. Add the missing
overloaded function and required headers.
Test: build/boot google/auron variants LULU ans SAMUS, verify
touchpad functional and no ACPI errors in kernel boot log.
