The am53c974/dc390 PCI interrupt has two separate sources: the first is from the internal ESP device, and the second is from the PCI DMA transfer logic. Update the ESP interrupt handler so that it sets DMA_STAT_SCSIINT rather than driving the PCI IRQ directly, and introduce a new esp_pci_update_irq() function to generate the correct PCI IRQ level. In particular this fixes spurious interrupts being generated by setting DMA_STAT_DONE at the end of a transfer if DMA_CMD_INTE_D isn't set in the DMA_CMD register.
