arm64: patching: Add aarch64_insn_write_literal_u64()
In subsequent patches we'll need to atomically write to a
naturally-aligned 64-bit literal embedded within the kernel text.
Add a helper for this. For consistency with other text patching code we
use copy_to_kernel_nofault(), which is atomic for naturally-aligned
accesses up to 64-bits.
