cbmem: Add support for new 'coreboot' compatible device tree binding

This patch brings the cbmem utility in line with the recent change to
coreboot's device tree binding. Since trying to find the right node to
place this binding has been so hard (and still isn't quite agreed upon),
and because it's really the more correct thing to do, this code searches
through the device tree for the 'coreboot' compatible property instead
of looking up a hardcoded path. It also provides bullet-proof
'#address-cells' handling that should work for any endianness and size.

BUG=chrome-os-partner:29311
TEST=Ran cbmem -c and cbmem -t on Nyan_Big. Also straced the to make
sure everything looks as expected. 'time cbmem -t' = ~35ms shows that
there is no serious performance problem from the more thorough lookup
code.
