We got requests from the field and they want to see a log to get know if 
FPGA configuration is successfully completed. They don't want use any 
additional command to get status.

This log is useful for the user who performs FPGA configuration.

I think we need use dev_info, since dev_dbg is not enabled by fault for 
most build.
