platform/chrome: cros_ec_proto: remove big stub objects from stack
sizeof(struct device) = 680
sizeof(struct cros_ec_dev) = 720
They tend to exceed the stack frame size limit in some specific
environment which results in the following compilation error:
>> drivers/platform/chrome/cros_ec_proto_test.c:2530:13: error: stack
frame size (2128) exceeds limit (2048) in
'cros_ec_proto_test_get_sensor_count_legacy'
Remove the big stub objects from stack.
This is:
$ sed -i 's/struct cros_ec_dev /static struct cros_ec_dev /' \
