And a PCI component depends on PciLib - that does not mean it should
live in edk2 MdePkg. And it does not mean that this library should be
considered Hisilicon-specific. If we get other platforms with this
component, they will not be permitted to add duplicated code - we
will then need to make sure the library is suitable for all users.

There is no situation other than the maintainers (me) dropping the
ball that lets you have a private driver for a generic component.

Regardless, I will leave this patch out for now, to avoid delaying the
release.
