s390/topology: Switch to common cpu capacity code

Browse source 
s390 implementation of cpu capacity management infrastructure code does
not do anything different than its common code counterpart. Switch to
common code functions and remove the smp_cpu_*_capacity() functions.
Make s390 code better align with other architectures which utilize
cpu_capacity. No functional changes.

Allow cpu_capacity attributes inside sysfs to accurately reflect cpu
capacity.
ex:

$ cat /sys/devices/system/cpu/cpu0/polarization
vertical:high
$ cat /sys/devices/system/cpu/cpu0/cpu_capacity
1024

$ cat /sys/devices/system/cpu/cpu40/polarization
vertical:low
$ cat /sys/devices/system/cpu/cpu40/cpu_capacity
128

Prior to commit 6bceea7a1e ("arch_topology: Relocate cpu_scale to
topology.[h|c]") cpu_capacity attribute was only available to the common
arch_topology driver's users. Reflect the correct values to the newly
made available attributes.
