The rationale is to allow the mainboard to override the default
baudrate for instance by sampling GPIOs at boot.
A new configuration option is available for mainboards to select
this behaviour. It will then have to define the function
get_uart_baudrate to return the computed baudrate.

The ATF tegra210 platform supports more than the currently used
'tzdram_size' parameter, see plat/nvidia/tegra/include/tegra_private.h

Add the missing parameters and set them accordingly. The passed UART id
is based on CONFIG_CONSOLE_SERIAL_TEGRA210_UARTx, so ATF now uses the
same port for console output as coreboot.
Successfully tested with UARTB.
