Add the new flags argument to calls of (devm_)gpiod_get*() and remove any direction setting code afterwards. Currently both forms (with or without the flags argument) are valid thanks to transitional macros in <linux/gpio/consumer.h>. These macros will be removed once all consumers are updated and the flags argument will become compulsary.
