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

Browse Source 
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.
