tty/serial: Fix break handling for PORT_TEGRA
When a break is received, Tegra's UART apparently fills the FIFO with
0 bytes. These must be drained so that they aren't interpreted as actual
data received. This allows e.g. MAGIC_SYSRQ to work on Tegra's UARTs.
v2: Added FIXME comment to clear_rx_fifo
