tools include UAPI: Sync sound/asound.h copy with the kernel sources

commit 4f2492731ada9d702ffdfaa6ec1ff64820a1664c upstream.

Picking the changes from:

  06feec6005c9d950 ("ASoC: hdmi-codec: Fix OOB memory accesses")

Which entails no changes in the tooling side as it doesn't introduce new
SNDRV_PCM_IOCTL_ ioctls.

To silence this perf tools build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/sound/asound.h' differs from latest version at 'include/uapi/sound/asound.h'
