[PULL 01/25] hw/input/pckbd: Open-code i8042_setup_a20_line() wrapper

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Since the named GPIO lines are a "public" interface to the device,
we can directly call qdev_connect_gpio_out_named(), making it
consistent with how the other A20 input source (port92) is wired.
