it's a bit odd to have different structures to stored 'booted_from_imr' and 'fw_context_save'. Can we put all the information in the same place?

@plbossart booted_from_imr is a intel feature which is set in sof/intel layer. fw_context_save is a common feature which is set in sof core layer. So I don't prefer to combine them in hda structure.

return 0;

/* the fw_lib has been verified during loading, we can trust the validity here */

why do we need the default value to be true?

It is for ref fw which supports it by default. Thanks @ujfalusi mentioned it for several times :)
