Fixed the lxdevel build by:
Moved some files that aren't really OLPC-specific from cpu/x86/pc/olpc into cpu/x86/pc and dev/geode, doing a little refactoring (mostly just moving code into different files) in the process.
Made lxdevel-specific versions of some files that contained OLPC dependencies
Removed spurious OLPC dependencies from the lxdevel build.
This change is intended to be functionally neutral for the OLPC build.
