board_ctrl: Clean up usage of VBUS, nARMED from user/kernelspace
Move logic implemented in the header files to source files, this way it will be simpler to define which is compiled to kernel space and which to user space Also allows to remove some headers that pull in half the universe from the board definitions (which should just be pin definitions and no functionality)
