With CONFIG_HNS3_HCLGE=y and CONFIG_HNS3_HCLGEVF=m, objects from
hns3/hns3_common are linked into a module and into vmlinux even
though the expected CFLAGS are different between builtins and
modules.
This is the same situation as fixed by
commit 637a642f5ca5 ("zstd: Fixing mixed module-builtin objects").
There's also no need to duplicate such big piece of object code into
two modules.
Introduce the new module, hclge_common, to provide the common
functions to both hclge and hclgevf.
Fixes: eaa5607db377 ("net: hns3: refactor hclge_cmd_send with new hclge_comm_cmd_send API")
Fixes: 1bfd6682e9b5 ("net: hns3: create new set of common rss get APIs for PF and VF rss module")
Fixes: 287db5c40d15 ("net: hns3: create new set of common tqp stats APIs for PF and VF reuse")

I'm curious how 40 Kb of shared code can be addressed differently :D
This Kconfig opt is hidden, it can only be selected by some other
symbol -- in this case, by the PF and VF HCLGE options. Nothing gets
exposed in a way it shouldn't be.
Lemme guess, some cross-OS "shared code" in the OOT nobody in the
upstream cares about (for good), how familiar :D IIRC ZSTD folks
also weren't happy at first.

I can export the common functions globally, without a namespace
if you prefer ._.
