hw/intc: Set GIC maintenance interrupt level to only 0 or 1

Browse Source 
During sbsa acs level 3 testing, it is seen that the GIC maintenance
interrupts are not triggered and the related test cases fail.  This
is because we were incorrectly passing the value of the MISR register
(from maintenance_interrupt_state()) to qemu_set_irq() as the level
argument, whereas the device on the other end of this irq line
expects a 0/1 value.

Fix the logic to pass a 0/1 level indication, rather than a
0/not-0 value.
