Stanley Chu 4a398c4ce4 UPSTREAM: scsi: ufs: Add trace event for UIC commands
Use the ftrace infrastructure to conditionally trace UFS UIC command
events.

New trace event "ufshcd_uic_command" is created, which samples the
following UFS UIC command data:

 - Device name
 - Optional identification string
 - UIC command opcode
 - UIC command argument1
 - UIC command argument2
 - UIC command argement3

Usage:
	echo 1 > /sys/kernel/debug/tracing/events/ufs/enable
	cat /sys/kernel/debug/tracing/trace_pipe
