tty: serial: imx: allow breaks to be received when using dma
This allows me to login after sending a break when service
serial-getty@ttymxc0.service is running
The "tty_insert_flip_char(port, 0, TTY_BREAK)" in clear_rx_errors
fixes this by allowing the higher layers to see a break.
Also, call uart_handle_break to handle possible
"secure attention key."
FYI: Martin said the ROM sdma firmware works with this patch,
but external sdma firmware still does not send breaks on a
i.mx6UL
