Remove FSP Rangeley SOC and mohonpeak board support

mohonpeak is the reference board for Rangeley. I doubt anyone uses it
or cares about it. We jokingly refer to it as "Moron Peak". It's code
with no known users, so we shouldn't be hauling it around for the
eventuality that someone might use it in the future.
