tools include UAPI: Sync sound/asound.h copy with the kernel sources
Picking the changes from:
37745918e0
("ALSA: timer: Introduce virtual userspace-driven timers")
Which entails no changes in the tooling side as it only introduces new
SNDRV_TIMER_IOCTL_ ioctls, and the ones tracked by scripts in
tools/perf/trace/beauty/ are only SNDRV_PCM_IOCTL_ and SNDRV_CTL_IOCTL_,
we still need to support SNDRV_TIMER_IOCTL_ ones, but that probably will
be one of the first for a BTF enumeration based approach :-)
This silences this perf tools build warning:
