Luiz Capitulino noticed that the tick_stop tracepoint wasn't being parsed

properly by the tracing user space tools. This was due to the
 TRACE_DEFINE_ENUM() being set to a define, when it should have been set
 to the enum itself. The define was of the MASK that used the BIT to shift.
 The BIT was the enum and by adding that, everything gets converted nicely.
 The MASK is still kept just in case it gets converted to an enum in the
 future.
