e57d6e9e20 mm/memory-failure: trace: change memory_failure_event to ras subsystem
Commit 97f0b13452 ("tracing: add trace event for memory-failure")
introduced memory_failure_event in ras subsystem.  commit 31807483d3
("mm/memory-failure: remove the selection of RAS") changed
memory_failure_event to memory_failure subsystem.  This breaks the
backward compatibility, some user programs rely on it.

Change memory_failure_event to ras subsystem to keep backward
compatibility.

31807483d3 mm/memory-failure: remove the selection of RAS
commit 97f0b13452 ("tracing: add trace event for
memory-failure") introduces the selection of RAS in memory-failure.  This
commit is just a tracing feature; in reality, there is no dependency
between memory-failure and RAS.  RAS increases the size of the bzImage
image by 8k, which is very valuable for embedded devices.

Move the memory-failure traceing code from ras_event.h to
memory-failure.h and remove the selection of RAS.
