Richard Genoud d2d8d4c049 tty/serial: atmel: remove unneeded atmel_get_lines_status function ...

Since commit 18dfef9c7f ("serial: atmel: convert to irq handling
provided mctrl-gpio"), the GPIOs interrupts are handled by
mctrl_gpio_irq_handle().
So, atmel_get_lines_status() can be completely killed and replaced by :
atmel_uart_readl(port, ATMEL_US_CSR);
