watchdog: octeon: Handle the FROZEN hot plug notifier actions.
When performing a suspend operation, the kernel brings all of the non-boot CPUs offline, calling the hot plug notifiers with the flag, CPU_TASKS_FROZEN, set in the action code. Similarly, during resume, the CPUs are brought back online, but again the notifiers have the FROZEN flag set. While some very few drivers really need to treat suspend/resume specially, this driver unintentionally ignores the notifications. This patch changes the driver to disable the watchdog interrupt whenever the CPU goes offline, and to enable it whenever the CPU goes back online. As a result, the suspended state is no longer a special case that leaves the watchdog active.
