ARM: dts: i.MX51: Separate TXD/RXD and RTS/CTS pinmux entries for UARTs
RTS/CTS pins can be used for different purposes, so create separate definitions for these pins. Signed-off-by: Alexander Shiyan <shc_work@mail.ru> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
