Add a best-effort probe function that tries all known DPFE versions to see if one might actually work. This helps in cases where device tree doesn't provide the proper version information for whatever reason. In that case, the driver may still be able to register if one of the known API versions ends up working. Caveat: we have to skip "v1" during our best effort attempts. This is due to the fact that attempting a firmware download as required by v1 will result in a memory access violation on anything but v1 hardware. This would crash the kernel. Since we don't know the HW version, we need to play it safe and skip v1. Signed-off-by: Markus Mayer <mmayer@xxxxxxxxxxxx>
