platform/chrome: Updates for 3.17

Updates to the Chromebook/box platform drivers:

- A bugfix to pstore registration that makes it also work on non-Google
  systems
- Addition of new shipped Chromebooks (later models have more probing
  through ACPI so the need for these updates will be less over time).
- A couple of minor coding style updates
