dts: ti: mspm0: Enable input for all UART RX pins
Added input-enable property to all UART RX pinmux entries across the MSPM0L222x pinctrl file to ensure proper input functionality for UART reception on all supported RX pins. Without the input-enable property, UART reception does not function correctly when the SoC enters low-power mode. Adding this property ensures reliable UART operation in all power states.
