x86: x86indebug command should print bit defintions
The chipset module prints debugging information about the state of
power good lines and chipset signals, but those have previously been
decodable only by looking at the EC source code.
Change the 'x86indebug' command to print a decoder ring.
BUG=chrome-os-partner:22895
BRANCH=none
TEST=x86indebug prints a list of bit meanings
