drm/lima: include pp bcast irq in timeout handler check

In commit 53cb55b202 ("drm/lima: handle spurious timeouts due to high
irq latency") a check was added to detect an unexpectedly high interrupt
latency timeout.
With further investigation it was noted that on Mali-450 the pp bcast
irq may also be a trigger of race conditions against the timeout
handler, so add it to this check too.
