cubieboard/qemu-armv7/am335x: Add fake TTB region for consistency
All ARM architecture boards are supposed to have a TTB region for their
page tables. ARM systems cannot use the data cache without enabling
paging, so it is imperative to do that as soon as possible. They will
also fault on unaligned accesses when not using the cache, which breaks
assumptions in CBFS code.
Unfortunately, we have some old boards in various stages of disrepair in
the tree that don't always follow these sorts of standard conventions.
It's not clear whether they actually boot anymore and if anyone still
has the respective hardware available to maintain them. I cannot really
fix and test them right now, but we should at least create a fake TTB
section for them so that common architecture code may make the correct
assumptions about which regions exist.
