this was discussed in
https://lists.freedesktop.org/archives/intel-gfx/2022-February/290821.html
... and that thread concluded it's cleaner to split the wait than try
to figure out hung-task configuration from middle of audio driver.

The 60sec timeout comes from 2019 patch "ALSA: hda: Extend i915 component 
bind timeout" to fix an issue reported by Paul Menzel (cc'ed).

This patch keeps the timeout intact.
