scsi: ufs: update ufs command logging infrastructure

Browse source 
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.
