firmware: cs_dsp: Add support for rev 2 coefficient files
Add support for the revision 2 coefficient file, this format is identical to revision 1 and was simply added by accident to some firmware. However unfortunately many firmwares have leaked into production using this and as such driver support really needs to be added for it.
