Subject: [PATCH] powerpc/cacheinfo: Make cpumap_show code reusable

References: jsc#SLE-13615 bsc#1180100 ltc#190257
Patch-mainline: v5.9-rc1
Git-commit: 74b7492e417812ea0f5002e210e2ac07a5728d17

In anticipation of implementing shared_cpu_list, move code under
shared_cpu_map_show() to a common function.

No functional changes.
