Add a capability for mainboard-specific posting.

Some mainboards have really nice capabilities for posting, beyond
    simple POST cards. Further, some can not use a POST card. This
    change defines a weak symbol (mainboard_post) that can be overridden
    by a real mainboard_post function.

If, for example, you'd like to do something fancy before the payload starts,
    you can add this to mainboard.c:

void mainboard_post(u8 value)
    {
    	switch(value){
    		case POST_TIME_TO_PARTY: some_fancy_lights();
    		break;
    	}
    }

Maybe the post function should be an entry in the device. We're beginning to over-use
    weak symbols.

BUG=None

TEST=Build and boot a google chromebook. Observe that it still works. Use it to drive
    some pretty lights.
