ARM: dts: imx53: add alternative UART2 configuration
UART2 on EIM_D26 - EIM_D29 pins supports interchanging RXD/TXD pins and RTS/CTS pins. One board using these alternate settings is Beckhoff CX9020. Add the alternative configuration here, to make it available to others, too. Signed-off-by: Patrick Bruenn <p.bruenn@beckhoff.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
