plat/xen: Include fp_arm64.c in FPSIMD Xen ARM64 builds

`fp_arm64.c` implements `fpsimd_save_state()` and `fpsimd_restore_state()` that are required by FPSIMD ARM64 builds. The file was not included in the build rules (in `Makefile.uk`) resulting in a build error. Fix the build error by including `fp_arm64.c` in the Xen build rules. This is similar to its inclusion in the KVM build rules.
