cbmem: add and use a function to dump console buffer
The new function can be compiled in only when serial console is
disabled.
When invoked, this function initializes the serial interface and dumps
the contents of the CBMEM console buffer to serial output.
BRANCH=none
BUG=chromium:475347
TEST=compiled for different platforms with and without serial console
enabled. No actual test of this function yet.
