Finn Thain 92178fcabb m68k/mac: Add mutual exclusion for IOP interrupt polling 
The IOP interrupt handler iop_ism_irq() is used by the adb-iop
driver to poll for ADB request completion. Unfortunately, it is not
re-entrant. Fix the race condition by adding an iop_ism_irq_poll()
function with suitable mutual exclusion.
