[PATCH 6/7] trace: Add an option for boot clock as trace clock

[John Stultz]

From: Joel Fernandes <joe...@google.com>

Unlike monotonic clock, boot clock as a trace clock will account for
time spent in suspend useful for tracing suspend/resume. This uses
earlier introduced infrastructure for using the fast boot clock.
