dtc: Remove remaining old-style checks

The remaining old-style tree checking code: check_root(), check_cpus()
and check_memory() really aren't that useful.  They mostly check for
the presence of particular nodes and properties.  That's inherently
prone to false-positives, because we could be dealing with an
artificial tree (like many of the testcases) or it could be expected
that the missing properties are filled in by a bootloader or other
agent.

If any of these checks really turns out to be useful, we can
reimplement them later in a better conceived way on top of the new
checking infrastructure.  For now, just get rid of them, removing the
last vestiges of the old-style checking code (hoorah).
