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.

+Subject: [PATCH 66/67] mb/dell: Add S3 SMI handler for Dell Latitudes
+
+Integrate the previously added mec5035_smi_sleep() function into
+mainboard code to fix S3 suspend on the SNB/IVB Latitudes and the E7240.
+The E6400 does not require the EC command to sucessfully suspend and
+resume from S3, though sending it does enable the breathing effect on
+the power LED while in S3. Without it, all LEDs turn off during S3.
