The function wkup_m3_rproc_boot_thread waits for asynchronous
firmware loading to complete successfully before calling
rproc_boot(). The same can be achieved by just setting
rproc->auto_boot flag. Change this. As a result this change
removes wkup_m3_rproc_boot_thread and moves m3_ipc->sync_complete
initialization to the wkup_m3_ipc_probe().
Other than the current usage, the firmware_loading_complete is
only used in rproc_del() where it's no longer needed. This
change is in preparation for removing firmware_loading_complete
completely.

Hi Suman,
Unfortunately, I don't have a TI device and couldn't test this
change. Is it possible for you to test this change on TI device?
Thanks in advance.
Regards,
Sarang
