[libvirt] [libvirt-python PATCH v2 2/2] Add support for virNodeGetSEVInfo

[Erik Skultety]

This binding allows to query the AMD's SEV firmware for various platform
specific things, like a PDH certificate and a certificate chain to
establish a trusted connection with the firmware. Because the API uses
typed params, it's exempted from generation.
