ASoC: Fixes for v6.19

We've been quite busy with fixes since the merge window, though not in
any particularly exciting ways - the standout thing is the fix for _SX
controls which were broken by a change to how we do clamping, otherwise
it's all fairly run of the mill fixes and quirks.

mm/memory-failure: remove the selection of RAS

commit 97f0b13452198290799f ("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.
