Sharing code was just a wild thought of mine, as I said I had not looked at
whether there is anything that can be shared.

However, simply moving drivers/net/ethernet/huawei/hinic to
drivers/net/ethernet/hisilicon/hinic/ still seems to be the right thing and
is a trivial patch.

It's clear that hinic is made by HiSilicon and that hns/hns3 are used
exclusively in Huawei, and maintained by Huawei developers, so it's
probably just a matter of time before the IP block from the SoC makes
it into a future PCI device or vice versa. Merging the two directories
now makes this easier to handle in the future and (slightly) reduces
the clutter in the top-level drivers/net/ethernet/Kconfig file.
