RISC-V: Do not emit zcisr and zifencei if i-ext is 2.0

I-ext 2.0 already included zicsr and zifencei, skip that prevent
confusing binutils.

gcc/ChangeLog

* common/config/riscv/riscv-common.c (riscv_subset_list::to_string):
Skip zicsr and zifencei if I-ext is 2.0.

(cherry picked from commit ca2bbb88f999f4d3cc40e89bc1aba712505dd598)
