This is a partial revert of patch "tty: Remove external interface for
tty_set_termios()" from Peter Hurley (2015-01-25 SHA1 632f32e2107) to
set tty_set_termios() publicly available.
This will be needed by Bluetooth hci_uart module to be able to change
Bluetooth controller and local UART speed during vendor specific
initialization.
