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

Picking the changes from:

  102882b5c6 ("ALSA: document that struct __snd_pcm_mmap_control64 is messed up")
  9f656705c5 ("ALSA: pcm: rewrite snd_pcm_playback_silence()")

Silencing these perf build warnings:

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