[PATCH 2/9] ARM: dts/at91: ensure UARTs used for rs485 specify rs485-rts-delay

[Uwe Kleine-König]

According to Documentation/devicetree/bindings/serial/rs485.txt the
rs485-rts-delay parameter is required. To prepare making use of
of_get_rs485_mode which is strict here, add this property to all at91
compatible devices that make use of one of the optional properties.
