amdfwtool: Put soc name setting to fw.cfg from command line

The fw.cfg should combine the SOC name.
This is for future combo feature. Each entry in combo has its own
fw.cfg.
The soc_id in struct cb_config can only be available after the fw.cfg
is processed.
Some functions which take soc_id as a parameter can be simplified.
