powerpc/rtas: lockdep annotations
Add lockdep annotations for the following properties that must hold:
* Any error log retrieval must be atomically coupled with the prior
RTAS call, without a window for another RTAS call to occur before the
error log can be retrieved.
* All users of the core rtas_args parameter block must hold rtas_lock.
Move the definitions of rtas_lock and rtas_args up in the file so that
__do_enter_rtas_trace() can refer to them.
