- Move main headers from include/ to include/main/
- Split booting logic to boot.c and boot-fdt.c to avoid cluttering main()
- Conditionally compile boot-fdt only if libfdt is used
- Add some better logging
Change was tested on qemu-virt, which succesfully booted a kernel:
$ qemu-system-aarch64 -machine virt -cpu cortex-a72 -nographic -m 512m -kernel uniLoader.o
