This platform had separate backends for the log subsystem and printk handler, which was silly. Unify them to use the same backend so they don't clobber each other. This patch appears to be a lot of lines, but it's really mostly code motion and renaming. Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
