[Qemu-devel] [PULL 07/22] IDE: MMIO IDE device control should be little endian

[Kevin Wolf <kwolf@redhat.com>]

From: Valentin Manea <valentin.manea@gmail.com>

Set the IDE MMIO memory type to little endian. The ATA specs identify
words part of the control commands encoded as little endian.
While this has no impact on little endian systems, it's required for big
endian systems(eg OpenRisc).
