    qemu-riscv: Remove obsolete CSR - send_ipi
    
    This aligns the code in qemu-riscv with the code in spike-riscv.
    The previous code gives an error in the updated toolchain as the
    send_ipi CSR is no longer valid.
    
    This gave the build error:
    src/mainboard/emulation/qemu-riscv/qemu_util.c:64:
       Error: Instruction csrw requires absolute expression
