ARM: at91/dt: introduce atmel,<chip>-dbgu

Browse source 
The DBGU is not a simple UART and we need to be able to distinguish it from the
other UARTs, in particular to get its address and check the chip id.

* Atmel Universal Synchronous Asynchronous Receiver/Transmitter (USART)
Required properties:
- compatible: Should be "atmel,<chip>-usart"
- compatible: Should be "atmel,<chip>-usart" or "atmel,<chip>-dbgu"
The compatible <chip> indicated will be the first SoC to support an
additional mode or an USART new feature.
For the dbgu UART, use "atmel,<chip>-dbgu", "atmel,<chip>-usart"
- reg: Should contain registers location and length
- interrupts: Should contain interrupt
- clock-names: tuple listing input clock names.
