[PATCH] cec-gpio: use GPIOD_OUT_HIGH_OPEN_DRAIN

[Hans Verkuil]

This driver needs a pull up output GPIO, but devm_gpiod_get() is called
with GPIOD_IN. This apparently works fine for the RPi3 where the DT
correctly specifies a pull up GPIO, but on the i.MX6 it also needs to
be specified with devm_gpiod_get().
