dt-bindings: serial: atmel,at91-usart: Add gclk as a possible USART clock
The Devicetree nodes for FLEXCOM's USART can also have an alternative clock source for the baudrate generator (other than the peripheral clock), namely the Generick Clock. Thus make the binding aware of this clock that someone may place in the clock related properties of the USART node.
