32ba9f0fb0 tools/bootconfig: Fix tracing_on option checking in ftrace2bconf.sh 
Since tracing_on indicates only "1" (default) or "0", ftrace2bconf.sh
only need to check the value is "0".

1eaad3ac3f tools/bootconfig: Use per-group/all enable option in ftrace2bconf script 
Use per-group/all enable option instead of ftrace.events option.
This will make the bootconfig file more readable.

55ed456077 tools/bootconfig: Add tracing_on support to helper scripts 
Add ftrace.instance.INSTANCE.tracing_on support to ftrace2bconf.sh
and bconf2ftrace.sh.

commit 8490db06f914 ("tracing/boot: Add per-instance tracing_on
option support") added the per-instance tracing_on option,
but forgot to update the helper scripts.

2b86062a34 tools/bootconfig: Add a script to generates bootconfig from ftrace 
Add a ftrace2bconf.sh under tools/bootconfig/scripts which generates
a bootconfig file from the current ftrace settings.

To read the ftrace settings, ftrace2bconf.sh requires the root
privilege (or sudo). The ftrace2bconf.sh will output the bootconfig
to stdout and error messages to stderr, so usually you'll run it as

 # ftrace2bconf.sh > ftrace.bconf

Note that some ftrace configurations are not supported. For example,
function-call/callgraph trace/notrace settings are not supported because
the wildcard has been expanded and lost in the ftrace anymore.
