When compiling with android toolchain, there is an instruction "str q0, [x8],#16", but x8 is not 16bytes aligned, this instruction will trigger sync abort.
So, following Linux kernel, only use general regs for arm64. If not, compiler may use simd registers Q[x]. We need to avoid using simd registers in U-Boot, because load/store Q[x] has restriction that 128bits aligned when str/ldr.
