ASoC: SOF: sof-client-probes-ipc4: Human readable debugfs "probe_points"
The current output of three integers is not very human readable. Use
ipc4 functions to describe in more detail what the struct
sof_probe_point_desc buffer_id is actually referring to in an ipc4 SOF
system.
Before this commit the "probe_points" debugfs file could read as:
Id: 0x01000004 Purpose: 0 Node id: 0x100
Id: 0x00000006 Purpose: 0 Node id: 0x100
And after in the same situation in an ipc4 system it reads:
0x7,0x0,0x100 gain.1.1 input buf idx 0 (connected)
0x1000005,0x0,0x100 host-copier.0.playback output buf idx 0 (connected)
The triplet in the beginning of the line can be used to reinserted the
probe point again by writing it into "probe_points" debugfs file, if
its first removed by writing the fist number in "probe_points_remove".
The last number is ignored when creating a probe point.
