Fix up and generalize the ITE IT8708F code. It was only working out of
pure luck (and broken code elsewhere). Needs some more fixing. Add more LDN descriptions to various Super I/Os. Signed-off-by: Uwe Hermann <uwe@hermann-uwe.de> Acked-by: Uwe Hermann <uwe@hermann-uwe.de> git-svn-id: svn://svn.coreboot.org/coreboot/trunk@2793 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
