From: Stefan Binding <sbinding@xxxxxxxxxxxxxxxxxxxxx>
CS42L42 runs jack detect on resume, however this requires unsol
events, and unsol events are ignored whilst the power state is
not set to ON. The power state is set to ON only after the resume
finishes. Schedule a delayed work timer to run jack detect
after the resume call finishes.
