exec: introduce endianness swapped mmio
The way we're currently modeling mmio is too simplified. We assume that every device has the same endianness as the target CPU. In reality, most devices are little endian (all PCI and ISA ones I'm aware of). Some are big endian (special system devices) and a very little fraction is target native endian (fw_cfg). So instead of assuming every device to be native endianness, let's move to a model where the device tells us which endianness it's in. That way we can compile the devices only once and get rid of all the ugly swap will be done by the underlying layer. For the same of readability, this patch only introduces the helper framework but doesn't allow the registering code to set its endianness yet.
