Refine various vendor ID annotations
This fixes a few vendor IDs to conform with JEDEC publication 106W (JEP106W), adds some device IDs and provides information about non-conforming IDs. The EON change is left to the patch adding EON chips. This patch should have no effect on code generation. Corresponding to flashrom svn r170 and coreboot v2 svn r3029.
