Summary:
- Add else statement to handle all condition of HSC module and 1ou card
type.
- Reformat array 'sensor_type_name' and 'sensor_status_name' to make it
easier to read.

Test Plan:
- Build Code: Pass

Summary:
- When HSC is ADM1278:
Default or 1ou is RBF, set HSC_OCP_GPIO1_R high.
If 2ou present, set HSC_OCP_GPIO3_R high, others low.
- When HSC is LTC4282:
Default or 1ou is RBF, set ILIM adjust to 0b001.
If 2ou present, set ILIM adjust to 0b011.

Test Plan:
- Build code: Pass

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.

Test Plan:
- Build Code: Pass

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