Currently the ftrace buffer shows durations in microseconds and modulo
1000000 us. It is problematic if values larger than one second are
measured.
This patch makes sure that no invalid value is ever displayed when an
overflow occurs. Instead, the trace will contain dashes, such as
"--------- us".
In addition, the unit is changed from microseconds (us) to milliseconds
(ms) when the duration exceeds a predefined value set by CFG_FTRACE_US_MS
(default: 10000 us).
