[arm/tegra] serial: Support for break on console driver.
There is sysrq feature which works from console with
sending break and then character.
The console driver uses the 8250 driver.
In tegra uart controller, after receiving break, it
needs to clear the rx fifo by reading fifo till empty
to receive the another break/character.
Fixing this issue in 8250 driver.
