arm64: Ensure fpsimd support is ready before userspace is active
We register the pm/hotplug callbacks for FPSIMD as late_initcall, which happens after the userspace is active (from initramfs via populate_rootfs, a rootfs_initcall). Make sure we are ready even before the userspace could potentially use it, by promoting to a core_initcall.
