intel/dev: Handle BSW naming issues

Browse source 
Braswell, a particular Cherryview variant, is especially strange.  We
can't even get the chip name from the PCI ID and instead have to look at
fusing information to decide if it's a 400 or a 405.  Pull that into the
common code as well.  This fixes BSW naming on ANV and crocus.
