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
