arm64: cpufeature: Pass capability structure to ->enable callback


From: Will Deacon <will.deacon@arm.com>

commit 0a0d111d40fd1dc588cc590fab6b55d86ddc71d3 upstream.

In order to invoke the CPU capability ->matches callback from the ->enable
callback for applying local-CPU workarounds, we need a handle on the
capability structure.

This patch passes a pointer to the capability structure to the ->enable
callback.
