ASoC: tracing: Export SND_SOC_DAPM_DIR_OUT to its value

Browse Source 
[ Upstream commit 58300f8d6a ]

The string SND_SOC_DAPM_DIR_OUT is printed in the snd_soc_dapm_path trace
event instead of its value:

   (((REC->path_dir) == SND_SOC_DAPM_DIR_OUT) ? "->" : "<-")

User space cannot parse this, as it has no idea what SND_SOC_DAPM_DIR_OUT
is. Use TRACE_DEFINE_ENUM() to convert it to its value:

   (((REC->path_dir) == 1) ? "->" : "<-")

So that user space tools, such as perf and trace-cmd, can parse it
correctly.
