Add support in kona machine driver to expose a sysfs node. Userspace uses this sysfs node to notify machine driver on which dai-link ( pcm id) is opened/closed. This information regarding device open/close is then compared against shutdown/ startup dai_link ops. If there is a mismatch we conclude that there has been a userspace service crash and we issue a close all session command to dsp and also clear all the dma buffers which were allocated by the service.
