arm64: stacktrace: make struct stackframe private to stacktrace.c
Now that arm64 uses arch_stack_walk() consistently, struct stackframe is only used within stacktrace.c. To make it easier to read and maintain this code, it would be nicer if the definition were there too. Move the definition into stacktrace.c. There should be no functional change as a result of this patch. Signed-off-by: Mark Rutland <mark.rutland@arm.com> Cc: Madhavan T.
