tools include UAPI: Sync sound/asound.h copy with the kernel sources
Picking the changes from:
08fdced60ca08e34 ("ALSA: rawmidi: Add framing mode")
Which entails no changes in the tooling side as it doesn't introduce new
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'
