tegra124: Make tegra124 compilable with serial turned off.

The bootblock and romstage UART consoles were being built in based only on
whether or not the bootblock and romstage consoles were selected, ignoring
whether serial console support was compiled in generally.

TEST=Built for nyan with and without serial.
