rS300969: Improve ARM debug_monitor for SMP machines

Summary

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.
