[PATCH 7/9] ARM: dts/imx: ensure UARTs used for rs485 specify rs485-rts-delay

["Uwe Kleine-König" <u.kleine-koenig-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>]

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 imx
compatible devices that make use of one of the optional properties.
