[PATCH RFC 3/8] arm64: stacktrace: Make callbacks use new prototype with frame info

[He Zhe <zhe.he@xxxxxxxxxxxxx>]

stack_trace_consume_fn has been changed to
bool (*stack_trace_consume_fn)(void *cookie, struct frame_info *fi);
to be able to pass more information.

Turn to use pc in struct frame_info in arch_stack_walk callbacks without
functinoal change.
