Add the atmel,usart-mode property to the UART nodes. This ensures
compliance with the atmel,at91-usart.yaml schema and resolves the errors
below:
serial@200: $nodename:0: 'serial@200' does not match
'^spi(@.*|-([0-9]|[1-9][0-9]+))?$'
serial@200: atmel,use-dma-rx: False schema does not allow True
serial@200: atmel,use-dma-tx: False schema does not allow True
serial@200: atmel,fifo-size: False schema does not allow [[16]]

These errors indicate that the property
atmel,usart-mode = <AT91_USART_MODE_SERIAL> is missing for
UART nodes 0, 1, 2, 3, 4, 6, 7, 8, 9, 10, 11, and 12.
