If SERIAL_MCTRL_GPIO is selected but GPIOLIB is not, the noop functions
from serial_mctrl_gpio.h are pulled in. However, serial_mctrl_gpio.c is
still compiled, leading to function redefinition build errors. Since all
drivers that include serial_mctrl_gpio.h also depend on
SERIAL_MCTRL_GPIO, let it depend on GPIOLIB as well remove the noop
functions alltogether.
