gpio: regmap: move drvdata to config data
Drop gpio_regmap_set_drvdata() and instead add it to the configuration
data passed to gpio_regmap_register().
gpio_regmap_set_drvdata() can't really be used in a race free way. This
is because the gpio_regmap object which is needed by _set_drvdata() is
returned by gpio_regmap_register(). On the other hand, the callbacks
which use the drvdata might already be called right after the
gpiochip_add() call in gpio_regmap_register(). Therefore, we have to
provide the drvdata early before we call gpiochip_add().
