ALSA: Convert timers to use timer_setup() 

In preparation for unconditionally passing the struct timer_list
pointer to all timer callbacks, switch to using the new timer_setup()
and from_timer() to pass the timer pointer explicitly. These are all the
"mechanical" changes remaining in the sound subsystem.
