           : Make reading fw_config from CBI and support other options as
           : fallback options and support backward compatiblity to support only one
           : option as before.

PS7, Line 408: config FW_CONFIG_SOURCE_CBFS
> Why move this?

Changing sequence is for following priority order or fallback order.
The order is 
1. FW_CONFIG_SOURCE_CHROMEEC_CBI
2. FW_CONFIG_SOURCE_CBFS
