Makfile: fix riscv extension isa problem

During building with tizen gcc, the below message is displayed.

[   13s] /home/abuild/rpmbuild/BUILD/opensbi-1.2/lib/sbi/sbi_tlb.c: Assembler messages:
[   13s] /home/abuild/rpmbuild/BUILD/opensbi-1.2/lib/sbi/sbi_tlb.c:190: Error: unrecognized opcode `fence.i', extension `zifencei' required
[   13s] make: *** [Makefile:503: /home/abuild/rpmbuild/BUILD/opensbi-1.2/build/lib/sbi/sbi_tlb.o] Error 1

This is same problem with linux-starfive and u-boot.
- not supported extension isa.

This patch will be abandoned when tizen gcc will be upper than GCC11.1.
