* Remove smp_lock.h from files which don't need it (including some headers!)
* Add smp_lock.h to files which do need it
* Make smp_lock.h include conditional in hardirq.h
It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT
This will make hardirq.h inclusion cheaper for every PREEMPT=n config
(which includes allmodconfig/allyesconfig, BTW)

This patch removes the unnecessary get/set input/audio functions.
The reason is, that the V4L2 specification says, that if input or audio
cannot be switched anyway, the functions doesn't need to be implemented.
I've tested the new driver with all current radio programs in
Debian/testing and found no problems with that.
In my opinion, the driver is much cleaner by removing these unnecessary
functions.
