I wouldn't do this on the bus in the first instance, I'd do it on the
device - it's pretty much orthogonal to the bus what the device wants
and it's perfectly plausible that a device on another bus might've made
unusual endiannness choices.  Otherwise it's pretty much what I was
thinking of.

For MMIO I'd expect that a large proportion of devices on platform buses
would pick native endianness.

Anything using format_write() can be ignored, it's already lost large
chunks of functionality just from that.  Non-integer byte sizes cause
issues.
