microblaze: Fix -Os right shift optimization is allowed into delay slot

During picolibc testing, it's found that `-Os` produces assembly code that compiler squeezes into a single delay slot. Thus, only the first instruction (the one in delay slot) emitted by this optimization is executed and the rest is skipped. Signed-off-by: Alp Sayin <[email protected]>
