CPU notifier is present for creating device
entries for child node "cache" under parent
node "cpu" as per DT. During resume from
suspend, while booting all non-boot CPU's,
this notifier for adding cache device gets
called before cpu device is added by
device_resume. Because of this warning message
of "parent should not be sleeping" comes during
resume.
Removing the notifier to explicitly add/remove
cache device as CPU and cache device get
added/removed anyway as part of normal suspend
resume sequence.
