Subject: arm64: cpufeature: Export this_cpu_has_cap helper

Git-commit: 20b02fe36530a1e48dde73c80b882ae276346ea3
Patch-mainline: v5.16-rc1
References: jsc#SLE-19046

Export the this_cpu_has_cap() for use by modules. This is
used by TRBE driver. Without this patch, TRBE will fail
to build as a module :

ERROR: modpost: "this_cpu_has_cap" [drivers/hwtracing/coresight/coresight-trbe.ko] undefined!

Fixes: 8a1065127d95 ("coresight: trbe: Add infrastructure for Errata handling")
