Modified Files:
        src/sys/arch/dreamcast/dev/g2: g2bus_bus_mem.c

Log Message:
Cleanup G2_LOCK/G2_UNLOCK macros per discussion on port-dreamcast:
- Use _cpu_intr_suspend()/_cpu_intr_resume() in G2_LOCK/G2_UNLOCK macros
  rather than _cpu_exception_suspend()/_cpu_exception_resume().
  TLB miss exceptions could happen on accessing buffer, but it will never
  block G2bus cycle anyway.
- Restore the previous SR.IMASK value in G2_UNLOCK().
- some misc cosmetics.

Should fix spontaneous reboots by "ping -s 8192 host" on the LAN Adapter.
