[Xiaojuan Yang]

This series patch add softmmu support for LoongArch.
Base on the linux-user emulation support V13 patch.

1638610165-15036-1-git-send-email-gaosong@loongson.cn/">https://patchew.org/QEMU/1638610165-15036-1-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 v3:
1.Target code mainly follow Richard's code review comments.
2.Put the csr and iocsr read/write instruction emulate into 2 different patch.
3.Simply the tlb emulation.
4.Delete some unused csr registers defintion.
5.Machine and board code mainly follow Mark's advice, discard the obsolete 
interface.
6.NUMA function is removed for it is not completed.
7.Adjust some format problem and the Naming problem 

Changes for v2:
1.Combine patch 2 and 3 into one.
2.Adjust the order of the patch.
3.Put all the binaries on the github.
4.Modify some emulate errors when use the kernel from the github.
5.Adjust some format problem and the Naming problem 
6.Others mainly follow Richard's code review comments.

Please help review!

Thanks
