AArch64: Add memset_zva64
Add a specialized memset for the common ZVA size of 64 to avoid the overhead of reading the ZVA size. Since the code is identical to __memset_falkor, remove the latter. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org> (cherry picked from commit 3d7090f14b13312320e425b27dcf0fe72de026fd)
