'Or' the IRQs coming from the QSPI and QSPI DMA models. This is done for
avoiding the situation where one of the models incorrectly deasserts an
interrupt asserted from the other model (which will result in that the IRQ
is lost and will not reach guest SW).

I noted this after receiving a review comment (from Peter Maydell) on a similar

Best regards,
Francisco Iglesias
