mb/google/eve: set ACPI subsystem ID
Set the ACPI SSID using Google's project campfire ID for EVE, to allow
coolstar's Windows drivers to identify the device (since it uses a
generic ACPI _HID). Custom drivers are necessary under Windows since
the touchpad firmware is not fully I2C-HID compliant.
TEST=build/boot Win11 on google/eve, verify touchpad fully functional.
