Feng Tang ed9b533747 DM: sos_bootargs: Add panic_print parameter to help debugging ...

Adding this parameter so that it could provide more info when
kernel panic happens. And this has almost no overhead as it only
uses several existing kernel APIs.

The 0x1f is a bitmask for type of info to be dumped, and it means
it will print task/memory/timer/lock/ftrace info when panic happens.
