[dpdk-dev] [PATCH 1/2] config/arm: fix Hisilicon kunpeng920 SoC build

[Lijun Ou <oulijun@huawei.com>]

From: Chengchang Tang <tangchengchang@huawei.com>

Because of the '9ca2f16' have merged, the current hns3
pmd driver can not be directly complied on the kunpeng920
server board. Therefore, we need to fix the meson build.
Besides, add kunpeng 920 SoC meson cross compile target.

Fixes: 9ca2f16faa7f ("config/arm: isolate generic build")
