scsi: ufs: update ufs command logging infrastructure 



This change increases the max command logging capability.
It also adds cmd log print if pwr ctrl failure detected.
Finally, it changes function name ufshcd_cmd_log_print to
ufshchd_print_cmd_log to align with the naming of other
ufshcd debug print functions.
