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

[Li Qiang]

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.
