When a CPU is shutdown either through CPU idle or suspend to RAM, the content of HW breakpoint registers must be reset or restored to proper values when CPU resume from low power states. This patch adds debug register restore operations to the HW breakpoint control function and implements a CPU PM notifier that allows to restore the content of HW breakpoint registers to allow proper suspend/resume operations.
