Min Hu (Connor) fa485faca2 net/hns3: update HiSilicon copyright syntax
According to the suggestion of our legal department,
to standardize the copyright license of our code to
avoid potential copyright risks, we make a unified
modification to the "Hisilicon", which was nonstandard,
in the main modules we maintain.

We change it to "HiSilicon", which is consistent with
the terms used on the following official website:
https://www.hisilicon.com/en/terms-of-use.

Fixes: 565829db8b ("net/hns3: add build and doc infrastructure")
Fixes: 952ebacce4 ("net/hns3: support SVE Rx")
Fixes: e31f123db0 ("net/hns3: support NEON Tx")
Fixes: c09c7847d8 ("net/hns3: support traffic management")
