powerpc/cacheinfo: Add per cpu per index shared_cpu_list
Unlike drivers/base/cacheinfo, powerpc cacheinfo code is not exposing
shared_cpu_list under /sys/devices/system/cpu/cpu<n>/cache/index<m>
Add shared_cpu_list to per cpu per index directory to maintain parity
with x86. Some scripts (example: mmtests
https://github.com/gormanm/mmtests) seem to be looking for
shared_cpu_list instead of shared_cpu_map.
Before this patch:
# ls /sys/devices/system/cpu0/cache/index1
coherency_line_size number_of_sets size ways_of_associativity
level shared_cpu_map type
# cat /sys/devices/system/cpu0/cache/index1/shared_cpu_map
00ff
#
After this patch:
# ls /sys/devices/system/cpu0/cache/index1
coherency_line_size number_of_sets shared_cpu_map type
level shared_cpu_list size ways_of_associativity
# cat /sys/devices/system/cpu0/cache/index1/shared_cpu_map
00ff
# cat /sys/devices/system/cpu0/cache/index1/shared_cpu_list
