Currently, the ath11k driver does not print a crash signature when a
crash happens. Checked by triggering a simulated crash using the command
[1] and checking dmesg for logs.
[1] echo assert > /sys/kernel/debug/ath11k/../simulate_fw_crash
Change the crash logging from debug to informational and add a warning
when firmware crash MHI_CB_EE_RDDM happens.
