soc/nvidia/tegra210: add missing bl31 params to ATF config 

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

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.
