Probe the UARTs on SEAD3 boards using device tree rather than platform code, in order to reduce the amount of the latter. This requires that CONFIG_SERIAL_OF_PLATFORM be enabled, so enable it in sead3_defconfig. The SEAD3 DT shim code is extended to read bootloader environment variables to determine the appropriate UART & mode for kernel console output & set the stdout-path property of the chosen node accordingly. In contrast to the old platform code, which appears to have only ever set "console=ttyS0,38400n8r" with the code in console_config never having an effect, this will honor the "yamontty" environment variable to select between the 2 UARTs on the board and then check the "modetty0" or "modetty1" variable as appropriate to determine the UART configuration.
