config/coreboot/default: Update MEC5035 patches

- Update the MEC5035 S3 patches to the versions that were sent upstream
  to prevent conflicts with subsequent patches for that EC.
- Update the patch that enables the S3 SMI handler in mainboard code so
  that all Latitudes use the handler.
- Add a new patch that tells the EC to route power button events to the
  host so that the OS can decide what to do. Without it, the EC powers
  off the system without letting the OS cleanly shut down.
