soc/nvidia/tegra210: set up the clock of the chosen UART
Don't always set up UARTA, but instead honor
CONFIG_CONSOLE_SERIAL_TEGRA210_UARTx and set up the clock of the
chosen UART.
Now the matching clock for the used UART is set up
(the UART driver uses CONFIG_CONSOLE_SERIAL_TEGRA210_UART_ADDRESS, which
in return is already based on CONFIG_CONSOLE_SERIAL_TEGRA210_UARTx).
