This series patch add softmmu support for LoongArch.
Base on the linux-user emulation support V9 patch.
  * https://patchew.org/QEMU/[e-mail]/diff/[e-mail]/

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.
4.Adjust some format problem.
5.Others mainly follow Richard's code review comments.

Please review!

Thanks
