Subject: e310/e320: Move E310 to MPM architecture and refactor

- Turns the E310 into an MPM device (like N3xx, E320)
- Factor out common code between E320 and E310, maximize sharing between
  the two devices
- Remove all pre-MPM E310 code that is no longer needed
- Modify MPM to remove all existing overlays before applying new ones
  (this is necessary to enable idle image mode for E310)
