Suspend/resume on am43xx-gpevm is broken right now in mainline and the regression looks
like it is caused by the display subsystem. I have reported this to Tomi and
its being investigated.

Meanwhile I have tested this patch with display configs disabled and Keerthy's
suspend/resume tests pass on both am3 and am4.

Thanks,
