Julien BERAUD 0fa362ff5c AP_Notify: Fix GPIO declaration for Linux boards
Currently, the default behaviour on linux boards tries to
write LED gpios with fixed values among them. There is no way
to declare that there are no LED GPIOs.
This commit moves the declaration of the LED Gpios in AP_HAL_Boards.h
and makes AP_Notify do nothing if no LED gpio was declared
