Add all necessary elements for DPDK to compile and run EAL on LoongArch64 Soc. This includes: - EAL library implementation for LoongArch ISA. - meson build structure for 'loongarch' architecture. RTE_ARCH_LOONGARCH define is added for architecture identification. - xmm_t structure operation stubs as there is no vector support in the current version for LoongArch. Compilation was tested on Debian and CentOS using loongarch64 cross-compile toolchain from x86 build hosts. Functions were tested on Loongnix and Kylin which are two Linux distributions supported LoongArch host based on Linux 4.19 maintained by Loongson Corporation. We also tested DPDK on LoongArch with some external applications, including: Pktgen-DPDK, OVS, VPP. The platform is currently marked as linux-only because there is no other OS than Linux support LoongArch host currently. The i40e PMD driver is disabled on LoongArch because of the absence of vector support in the current version. Similar to RISC-V, the compilation of following modules has been disabled by this commit and will be re-enabled in later commits as fixes are introduced: net/ixgbe, net/memif, net/tap, example/l3fwd.
