CPU and APB Frequency support (#2220)

Browse Source 
* Add support to HAL for APB frequencies different than 80MHz

* Add support for CPU frequencies in the IDE board menu

* Switch to fast set_config

* Add method to uart so debug can be reassigned after apb frequency switch

* Return real APB frequency
