1. Move run_bios prototype to device.h

Browse Source 
2. Use time.h for get_time() and move tb_freq into functions.c
3. Move read_io and write_io to io.c and make them static
4. Make a couple of functions static in interrupt.c
5. Refactor a cast from char[] to u64 to get rid of potential alignment problems and a warning
