ftrace: enable trace_printk by default
Impact: have the ftrace_printk enabled on startup It is confusing to have to "echo trace_printk > /debug/tracing/iter_ctrl" after adding ftrace_printk in the kernel. Currently the trace_printk is set to off by default. ftrace_printk should only be in open kernel code when used for debugging, and thus it should be enabled by default. It may also be used to record data within a tracer, but those ftrace_printks should be within wrappers that are either enabled by trace_points or have a variable protecting the code path from being entered when the tracer is disabled.
