Completely rip out / replace the ASUS P2B code (which wasn't really working),

replacing it with a minimal, but working, framework which will be expanded.
Drop a bunch of useless and duplicated files, add missing license headers.

I'm self-acking it this time, the diff is a huge unreadable mess and the old
code is broken anyway...

This code is tested to build fine, and can boot a Linux kernel up to a
login-prompt via FILO (IDE). This is verified on actual hardware.
