Improve ARM debug_monitor for SMP machines

- Reset debug architecture and enable monitor for secondary
  CPUs in init_secondary() rather than when configuring watchpoint, etc.
- Disable HW debugging capabilities when one of the CPU cores fails
  to set up.
- Use dbg_capable() in a more atomic manner to avoid any mismatch
  between CPUs.
