gpu: ipu-v3: fix a possible NULL dereference of_match_device could return NULL, and so cause a NULL pointer dereference later. For fixing this problem, we use of_device_get_match_data(), this will simplify the code a little by using a standard function for getting the match data. Testing the return value of of_device_get_match_data is also necessary for avoiding a second NULL deref later on devtype.
