So keep only the subsets that we need in memory, depending on the debug config). Also, in doing so, we can remove all the calls to iwl_bt_statistics() in the driver as we'll just access the copied statistics now. Finally, also remove this call from the one place where it might still be needed and automatically detect what kind of statistics the device is sending based on their size. This way, we don't need to keep track of which devices do what any more, which is good since this is subject to change based on the ucode version (as some ucode even for non-BT devices will in fact use BT statistics). Warn upon encountering a statistics command from the ucode that isn't known, so we will find such issues earlier in the future.
