glados: Enable DPTF
- Add ACPI code for DPTF support with placeholder thresholds
- Do not have custom PDL for mainboard
- Do not have enable charger control for DPTF as there is
already a complicated charge profile in the EC. We may still
want to enable this but it would need to be tuned to work
well with the EC profile.
