Coding-style fixes and simplifications for the ASUS A8N-E (trivial).
The only non-cosmetic change is s/A8NE/A8N-E/ for the board name. This is build-tested by me. 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@3622 2b7e53f0-3cfb-0310-b3e9-8179ed1497e1
