[PVE-User] Host's GPIO access from within different VMs running in pve.

[Hongyi Zhao]

I noticed the explanations on the general-purpose input/output (GPIO)
on the wiki: <https://en.wikipedia.org/wiki/General-purpose_input/output>.

But I still don't know the specific access method of the GPIO on the
host's motherboard from within different VMs running in pve. Any hints
will be highly appreciated.
