ARM64: smp: fix incorrect per-cpu definition of regs_before_stop
The commit f3b4a40bc637a25c01c5ec66c825b4ddfc30328a introduced changes
to store CPU registers for all CPUs that handle IPI_CPU_STOP. The
structure to save the registers was intended to be a per-cpu variable.
However, the patch did not allocate a per-cpu structure and instead only
ended up providing a compiler per-cpu directive. Fix this bug by actually
defining a static per-cpu variable.
