ARM: dts: imx7d-pinfunc: add input mux for UART2 RX DTE mode Add input mux for UART2 RX in DTE mode. This allows to use the pad UART2_TX_DATA_ALT0 as UART2 RX. This particular input select seems to be missing in current reference manuals (Rev. B), but when looking at the tables and other UART input select registers (e.g. UART3) it seems naturally that this input mux register also has a fourth pad option for UART2_TX_DATA_ALT0. It has also been proven to be required to use UART2 in DTE mode and the particular pads on the Colibri iMX7 platform.
