I doubt Arcturus MP1 really supports ACDC switch and probably even doesn't have
smc message to ack the interrupt as well. If so, the interrupt_work function
shall not be necessary for Arcturus. Other than that

Subject: [PATCH 2/2] drm/amdgpu/swsmu: add interrupt work handler for smu11
parts
We need to schedule the smu AC/DC interrupt ack to avoid potentially sleeping
if the smu message mutex is contended.
