The i.MX7 has two iomux controllers. the iomuxc and the iomuxc_lpsr.
In a board dts we have to make sure that both controllers are supplied
with the correct pins. It's way too easy to do this wrong since only
a look into the reference manual can reveal which pins belong to which
controller. To make this clearer add "LPSR" to the pin names which
belong to the LPSR controller.

The UART pinmux defines for the pins which are part of the LPSR
pinmux controller are wrong: Output signals configure the input
sel value and the pinmux defines allow not to distinguish between
DCE/DTE mode. Follow the usual pattern using DTE/DCE as part of
the define to denote the two UART configuration options.

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.
