Well there is a pending rework of these optional peripherals for sam9x5 
series. So we may end-up with this usart3 declaration in a separated 
file that will be included in both sam9g25 and sam9x25 product 
descriptions (together with the already existing pinctrl declaration 
that resides in at91sam9x5.dtsi).

So, I keep your code and will try to make sure that it is included 
during the move to that model. If you do not see it appearing, please 
remind us then...

Thanks a lot, bye,
