[v3 00/24] Support LoongArch architecture

[Min Zhou <zhoumin@loongson.cn>]

Dear team,
The following patch set is intended to support DPDK running on LoongArch
architecture.

LoongArch is the general processor architecture of Loongson and is a new
RISC ISA, which is a bit like MIPS or RISC-V.

The online documents of LoongArch are here:
	https://loongson.github.io/LoongArch-Documentation/README-EN.html

The latest cross compile tool chain can be downloaded from:
	https://github.com/loongson/build-tools

v3:
    - add URL for cross compile tool chain
	- remove rte_lpm_lsx.h which was a dummy vector implementation
      because there is already a scalar implementation, thanks to
      Michal Mazurek
    - modify the name of compiler for cross compiling
    - remove useless variable in meson.build

v2:
    - use standard atomics of toolchain to implement
      atomic operations
    - implement spinlock based on standard atomics
