[Qemu-devel] [PATCH v2 1/3] edu: mmio: set 'max_access_size' to 8 |

The edu spec said, the MMIO area can be accessed by 8 bytes.
However currently the 'max_access_size' is not so the MMIO
access dispatch can only access 4 bytes one time. This patch
fixes this to respect the spec.
Notice: here the 'min_access_size' is not a must, I set this
for completement.
