For each device declared with DEVICE_NATIVE_ENDIAN, find the set of
targets from the set of target/hw/*/device.o.

If the set of targets are all little or all big endian, re-declare
as DEVICE_LITTLE_ENDIAN or DEVICE_BIG_ENDIAN respectively.

Then, on inspection:
- if not used, re-declare as DEVICE_HOST_ENDIAN.
- if max/min size=1, re-declare as DEVICE_HOST_ENDIAN.
- if just a bit bucket, re-declare as DEVICE_HOST_ENDIAN
- if PCI, re-declare as DEVICE_LITTLE_ENDIAN.
- if for {ARM|unicore32} only, re-declare as DEVICE_LITTLE_ENDIAN.
- if for SPARC only, re-declare as DEVICE_BIG_ENDIAN.
