Refactor async console output

This adds a 'ch' command which prints/sets which channels are active

This handles all the async output; the remaining debug commands will
be refactored to use ccprintf() / ccputs() in a followup CL.

Signed-off-by: Randall Spangler <rspangler@chromium.org>

BUG=chrome-os-partner:7464
TEST=manual

ch --> all channels active
ch 0x100 -> just port80 active
powerbtn -> system boots; only port 80 codes shown on console
