[PULL 28/36] hw/sd/omap_mmc: Convert output qemu_irqs to gpio and sysbus IRQ APIs

[Philippe Mathieu-Daudé]

From: Peter Maydell <peter.maydell@linaro.org>

The omap_mmc device has three outbound qemu_irq lines:
 * one actual interrupt line
 * two which connect to the DMA controller and are signalled for
   TX and RX DMA

Convert these to a sysbus IRQ and two named GPIO outputs.
