x86, intel_txt: clean up the impact on generic code, unbreak non-x86
Move tboot.h from asm to linux to fix the build errors of intel_txt patch on non-X86 platforms. Remove the tboot code from generic code init/main.c and kernel/cpu.c. Signed-off-by: Shane Wang <shane.wang@intel.com> Signed-off-by: H. Peter Anvin <hpa@zytor.com>
