tty/serial/8250: use mctrl_gpio helpers This patch permits the usage for GPIOs to control the CTS/RTS/DTR/DSR/DCD/RI signals. Changed by Stefan: Only call mctrl_gpio_init(), if the device has no ACPI companion device to not break existing ACPI based systems. Also only use the mctrl_gpio_ functions when "gpios" is available. Use MSR / MCR <-> TIOCM wrapper functions.
