With this, TARGET_PAGE_BITS_MIN no longer exists outside of
page-vary-target.c, as that's the only place that needs the
information.

Which is a lot, so for avoidance of doubt:

I'll rebase my hw/arm single binary series 'single-binary: start make 
hw/arm/ common' on top of this series, so we can continue to expand the 
house of cards for this topic.

Feel free to pick the cpu-all cleanup part if it's interesting and ready 
for you.
