arm64: stacktrace: move SDEI stack helpers to stacktrace code

For clarity and ease of maintenance, it would be helpful for all the
stack helpers to be in the same place.

Move the SDEI stack helpers into the stacktrace code where all the other
stack helpers live.

There should be no functional change as a result of this patch.
