From: Uwe Kleine-König <u.kleine-koenig@xxxxxxxxxxxxxx>
To be able to make use of the mctrl-gpio helper from a module these
functions must be exported. This was forgotten in the commit introducing
support interrupt handling for these functions (while it was done for
mctrl_gpio_enable_ms, *sigh*).
Fixes: ce59e48fdbad ("serial: mctrl_gpio: implement interrupt handling")
