Import __do_div64 from Linux 4.4.6 , commit 0d1912303e54ed1b2a371be0bba51c384dd57326 on arm32. This function is for some toolchains, which generate _udivmoddi4() for 64 bit division. Since we do not support stack unwinding, instead of importing the whole asm/unwind.h and all the baggage, this patch defines empty UNWIND() macro. This patch also defines CONFIG_THUMB2_KERNEL and CONFIG_ARM_ASM_UNIFIED which is necessary for correct build of these files both in ARM and Thumb mode, just like Linux does.
