Fby3.5 hd support bom3 sensor (#468)

Summary:
- Support VR sensor MP2856GUT
- Add the sensor config table of 3rd source sensor, replace sensor talbe to it if board revision is SYS_BOARD_EVT_BOM3.

Dependency: #467

Pull Request resolved: #468

Test Plan:
- Build Code: Pass

Known issue:
- Pout reading for MP2856GUT is larger than expected, still checking with FAE.
