soc/intel: hook up new gpio device in the soc chips
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.
