perf trace beautify ioctl: Beautify sound ioctl's 'cmd' arg
This time we try a new approach, using a copy of uapi/sound/asound.h we
auto generate the string tables, then include it in the ioctl cmd
beautifier.
This way either the sound developers will add the new commands to the
tools/ copy, like is happening with other areas of tools/include/ (bpf.h
comes to mind), or we'll be notified when building perf that our copy
drifted.
E.g.:
# perf trace -p 22084 -e ioctl 2>&1 | head -5
0.000 ( 0.068 ms): alsa-sink-ALC3/22084 ioctl(fd: 49</dev/snd/pcmC1D0p>, cmd: SNDRV_PCM_HWSYNC, arg: 0x557f8d7fa0f0) = 0
