Andrzej Kacprowski 72f7e16ecc accel/ivpu: Fix NOC firewall interrupt handling
The NOC firewall interrupt means that the HW prevented
unauthorized access to a protected resource, so there
is no need to trigger device reset in such case.

To facilitate security testing add firewall_irq_counter
debugfs file that tracks firewall interrupts.
