Mark Cave-Ayland 442de89a93 esp.c: keep track of the DRQ state during DMA ... Currently the DRQ IRQ is updated every time DMA data is sent/received which is both inefficient and causes excessive logging of the DRQ state. Add a new drq_state bool that only updates the DRQ IRQ if its state changes. This commit adds the new drq_state bool to the migration state: since the version number has already been increased earlier in the series, there is no need to repeat it again here. The DRQ IRQ is (currently) only used for PDMA transfers which already have a migration break in this series so there are no problems setting its value post-load.
