forked from Mirror/GodMode9

- added initial SCU twiddling - added very untested and unusable SMP code - fixed race condition that happened on boot - added initial MMU code (just super basic identity mapping, no caching set up or anything) - enabled some of the fancier ARMv6 features - reorganized ARM11 files into their own folders - possibly more stuff I'm forgetting about
