The driver does not access reset GPIO in atomic contexts so it is usable
with GPIOs that may sleep during access. Switch to using
gpiod_set_value_cansleep().

Also the reset GPIO is configured as output at the time it is acquired,
there is no need to use gpiod_direction_output() when executing reset
sequence.
