This PR fixes the problem mentioned in Issue #210 .
The symbol irq_regs in firmware/start.S is possibly unaligned when compiled to support compressed instructions. However, irq_regs is further loaded into sp register and involved in memory access, which results in unaligned memory access problem.
This PR forces irq_regs to always be aligned with .balign 0x200, by doing this solves the problem.
