powerpc/pmac/smp: Add missing FROZEN hotplug notifier transitions
The FROZEN transitions are used when a CPU suspends/resumes. In case
of a suspend/resume, only the up prepare (CPU_UP_PREPARE_FROZEN) is
handled. The error handling transition CPU_UP_CANCELED_FROZEN as well
as the CPU_ONLINE_FROZEN transition are not handled.
Masking the switch case action argument with ~CPU_TASKS_FROZEN, to
handle all FROZEN tasks the same way than the corresponding non frozen
tasks.
