Subject: soc/intel: hook up new gpio device in the soc chips
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This change adds the required gpio operations struct to soc/common gpio
code and hooks them up in all socs currently using the gpio block code,
except DNV-NS, which is handled in a separate change.

Also, add the gpio device to existing chipset devicetrees.

Successfully tested on Supermicro X11SSM-F with CB:48097, X11SSH-TF with
CB:48711 and OCP DeltaLake with CB:48672.
