Merge tag 'at91-cleanup2' into at91-4.1-multiplatform 

Second batch of cleanup for 4.1:
- remove unused matrix header files
- dbgu + chip identification: new driver for SoC detection
  this allow to remove all additional io mapping
- remove old non-standard AT91 setup code

* 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.
