drm/ci: update device type for volteer devices

Volteer devices in the collabora lab are categorized under the
asus-cx9400-volteer device type. The majority of these units
has an Intel Core i5-1130G7 CPU, while some of them have a
Intel Core i7-1160G7 CPU instead. So due to this difference,
new device type template is added for the Intel Core i5-1130G7
and i7-1160G7 variants of the Acer Chromebook Spin 514 (CP514-2H)
volteer Chromebooks. So update the same in drm-ci.
