The logger currently blocks in open for finding SOH within the circular buffer. This blocking is infinite. However, the SOH is written in buffer for sure when adsp boots. Hence, added a check to see if in the past if adsp has been started and then search for SOH else return an error. Also, the blocking takes place in the read path where the logger waits in the position where it gets EOT and loops back. This is not desirable due to recent changes in debugfs and hence now the read path returns back with an ASCII value of BELL which will not effect `cat` from writing anything on the console.
