Implement BMC position for RBMC prototype system

BMC’s role in RBMC prototype system is determined based on its
position.

This commit adds the code to implement BMC position for RBMC
prototype system based on whether BMC has access to motherboard EEPROM
or not.

Test:
```
Tested the changes by keeping lab system IM value in constants file, observed that position interface is created for the system.
