[PATCH 1/2] i2c-mux-gpio: use gpio_set_value_cansleep()

[Ionut Nicu <ioan.nicu.ext-OYasijW0DpE@public.gmane.org>]

Some gpio chips may have get/set operations that
can sleep. gpio_set_value() only works for chips
which do not sleep, for the others we will get a
kernel warning. Using gpio_set_value_cansleep()
will work for both chips that do sleep and those
who don't.
