    aarch64: Restrict SME_LUTv2 instructions to streaming mode
    
    These instruction definitions were incorrectly missing their streaming
    mode requirement.
    
    gcc/ChangeLog:
    
            * config/aarch64/aarch64-sme.md
            (aarch64_sme_write_zt): Add TARGET_STREAMING requirement.
            (aarch64_sme_lut_zt): Ditto.
