This series patch add softmmu support for LoongArch.
Base on the linux-user emulation support V9 patch.
  * https://patchew.org/QEMU/1630586467-22463-1-git-send-email-gaosong@loongson.cn/diff/1636340895-5255-1-git-send-email-gaosong@loongson.cn/

The latest kernel:
  * https://github.com/loongson/linux/tree/loongarch-next
The manual:
  * https://github.com/loongson/LoongArch-Documentation/releases/tag/2021.10.11

Changes for v2:
1.Combine patch 2 and 3 into one.
2.Adjust the order of the patch.
3.Modify some emulate errors when use the kernel from the github.
