[PATCH linux-next] Driver core: cpu: remove not needed anymore hotplugable_cpu_attr_groups[]

[Igor Mammedov <imammedo@redhat.com>]

after fixing conflict between
0902a9044 "Driver core: Use generic offline/online
for CPU offline/online"

and

1c4e2d70a "cpu: make sure that cpu/online file created
before KOBJ_ADD is emitted"

there was left some not needed remnants of the last
commit, remove them since the first commit does the
same thing in another way.

Signed-off-by: Igor Mammedov <imammedo@redhat.com>

PS:
Alernative way is just to drop 1c4e2d70a if rebase of tree
is acceptable.
