mmc: renesas_sdhi: take DMA end interrupts into account
So far, we have been relying on access_end interrupts only to mark DMA
transfers as done implying that DMA end interrupts have occurred by then
anyhow. On some SoCs under some conditions, this turned out to be not
enough. So, we enable DMA interrupts as well and make sure that both
events, DMA irq and access_end irq, have happened before finishing the
DMA transfer.
