This removes the BKL from the various open functions that do not need it, or only use it to protect an open count. The zoran driver is nontrivial in this regard, so I introduce a new mutex that locks both the open/release and the ioctl functions. Someone with access to the hardware can probably improve that by using the existing lock in all cases. Finally, all drivers that still use the locked version of the ioctl function now get called under a new mutex instead of the BKL.

These are all simple conversions: most already had a lock and so the ioctl fop could simply be replaced by unlocked_ioctl. radio-miropcm20.c was converted to use the new V4L2 core lock. While doing this work I noticed that many of these drivers initialized some more fields or muted audio or something like that *after* creating the device node. This should be done before the device node is created to prevent problems. Especially hal tends to grab a device node as soon as it is created. In one or two cases the mutex_init was even done after the device creation!

While it would be possible to fix the issue, there are some other lock troubles, like to the presence of lock code at free_btres_lock(). It is possible to fix, but the better is to just use the core-assisted locking schema. This way, V4L2 core will serialize access to all ioctl's/open/close/mmap/read/poll operations, avoiding to have two processes accessing the hardware at the same time. Also, as there's just one lock, instead of 3, there's no risk of dead locks. The net result is a cleaner code, with just one lock.
