There should be just one timer resolution in ns member (like in struct
snd_timer_ginfo - not frame/period members here - it's too specific). The
resolution can be calculated in the user space from the rate and period size.
Also naming - the timer API uses snd_timer prefix for structures, thus
snd_timer_uinfo should be more appropriate.
