tegra124: Add a test function which spams exclamation points on the UART.

This function spews characters on the console and, until we have a working
console, is an easy way to see whether the system boots to a particular point.
For some reason waiting for transmitter to be empty hangs, but transmitting
characters still works.

BUG=None
TEST=Enabled the function and saw the UART output.
BRANCH=None
