Missing review: 2, 13 to 16.

Since v3:
- Addressed Thomas review comments

Since v2:
- Addressed Richard's review comments

Since v1:
- Make device endianness configurable (Edgar)
- Convert more Xilinx devices
- Avoid preprocessor #if (Richard)
- Add R-b tags

Make machines endianness-agnostic, allowing to run a big-endian vCPU
on the little-endian 'qemu-system-microblazeel' binary, and a little
endian one on the big-endian 'qemu-system-microblaze' binary.

Tests added, following combinations covered:
- little-endian vCPU using little-endian binary (in-tree)
- little-endian vCPU using big-endian binary (new)
- big-endian vCPU using little-endian binary (new)
- big-endian vCPU using big-endian binary (in-tree)

To make a target endian-agnostic we need to remove the MO_TE uses.
In order to do that, we propagate the MemOp from earlier in the
call stack, or we extract it from the vCPU env (on MicroBlaze the
CPU endianness is exposed by the 'ENDI' bit).

Next step: Look at unifying binaries.

Please review,

Phil.
