ARM: kexec: record parent context registers for non-crash CPUs
How we got to machine_crash_nonpanic_core() (iow, from an IPI, etc) is
not interesting for debugging a crash. The more interesting context
is the parent context prior to the IPI being received.
Record the parent context register state rather than the register state
in machine_crash_nonpanic_core(), which is more relevant to the failing
condition.
