ASOC: SOF: Intel: hda-loader: only wait for HDaudio IOC for IPC4 devices

Browse Source 
[ Upstream commit 9ee3f0d8c9 ]

Multiple users report a regression bisected to commit d5263dbbd8
("ASoC: SOF: Intel: don't ignore IOC interrupts for non-audio
transfers"). The firmware version is the likely suspect, as these
users relied on SOF 2.0 while Intel only tested with the 2.2 release.

Rather than completely disable the wait_for_completion(), which can
help us gather timing information on the different stages of the boot
process, the simplest course of action is to just disable it for older
IPC versions which are no longer under active development.
