riscv: use NULL instead of a plain 0
sbi_remote_sfence_vma() & sbi_remote_fence_i() takes a pointer as first argument but some macros call them with a plain 0 which, while legal C, is frowned upon in the kernel. Change this by replacing the 0 by NULL. Signed-off-by: Luc Van Oostenryck <luc.vanoostenryck@gmail.com> Signed-off-by: Palmer Dabbelt <palmer@sifive.com>
