ac/gpu_info: if clock crystal frequency is 0, print an error and set 1
During bring-up, this is often 0. Prevent automatic disablement of ARB_timer_query and demotion of the OpenGL version to 3.2 by setting a non-zero frequency. Print an error message instead. Reviewed-by: Nicolai Hähnle <[email protected]>
