    RISC-V: Refactor vxrm_mode attr for type attr equal
    
    This patch would like to refactor the vxrm_mode attr for duplicated
    eq_attr condition. The common condition of attr is extraced to one
    place instead of many places.

            * config/riscv/vector.md: Refactor the common condition.
