    RISC-V: Remove duplicate command-line parsing logic
    
    builtin_cmdline handling is present in drivers/of/fdt.c so the
    duplicate logic in arch/riscv/setup.c results in duplication of
    the builtin command line. e.g. CONFIG_CMDLINE="root=/dev/vda ro"
    gets appended twice and gives "root=/dev/vda ro root=/dev/vda ro"
    
    Before this patch:
    
    [    0.000000] Kernel command line: root=/dev/vda ro root=/dev/vda ro
    
    After this patch:
    
    [    0.000000] Kernel command line: root=/dev/vda ro
