Subject: [PATCH 3/3] LoongArch: Add stacktrace support

Use common arch_stack_walk infrastructure to avoid duplicated code and
avoid taking care of the stack storage and filtering.
Add sra (means __schedule return address) and scfa (means __schedule call
frame address) to thread_info and store it in switch_to().

Now we can print the process stack by cat /proc/*/stack and can better
support ftrace.
